Beginning from ancient times when prehistoric peoples began using fire, humankind has relied on the use of thermal energy to keep warm, cook food, and make tools. Thermal energy derived from combustion or oxidation of fuel materials or obtained from the sun's rays has proven essential to human flourishing. The transfer of thermal energy from one substance to another provides heat for warming objects and spaces, for altering the chemical properties of materials, and for changing their shapes. Certain devices for producing thermal energy (each, a “thermal device”), including without limitation equipment such as furnaces, boilers, heaters, warmers, ovens, stoves, dryers, annealers, bakers, cookers, sealers, smelters, solderers, torches, cutting torches, welders, melters, kilns, autoclaves, sterilizers, and the like are well-known in everyday life, while others are familiar to artisans of ordinary skill in more specialized fields.
Thermal energy is the total kinetic energy of a solid or fluid object or material medium due to the random motion of its atoms and molecules. Temperature is the average kinetic energy within the object. Heat is the transfer or flow of thermal energy due to differences in temperature between one object/material medium and another, with the heat flowing from the higher-temperature object/material medium to the one with a lower temperature. Thermal energy is transferred by conduction, convection, and radiation.
Thermochemical principles, whereby chemical reactions are incited to produce thermal energy, are employed routinely for residential or industrial purposes. In many cases, the thermal energy is captured by another medium or mechanism to produce useful work, as is seen in internal or external combustion engines, in which the heat produced by combustion expands fluids (gases or liquids) to drive a prime mover mechanical part, thereby producing useful work, i.e., the displacement of the mechanical part. In other cases, however, the production of heat is itself the goal of the chemical reaction. For example, the chemical reaction of combustion in fireplaces and stoves produces thermal energy that is used to heat spaces and to heat food; in these situations, the beneficial effect of the chemical reaction is not measurable secondarily as work (i.e., the displacement of an object produced by a force acting on it), but rather is quantified primarily as heat. Thermal energy used to produce heat for residential and industrial applications is most commonly derived either directly or indirectly from conventional fossil fuel sources. This results in the production of CO2, which subsequently enters the atmosphere as a greenhouse gas.
It is estimated that heating an average American home with natural gas produces about 6,400 pounds of carbon dioxide, and heating with electricity produces about 4,700 pounds. In colder regions, however, the average amount of CO2 for home heating can double. Commercial settings have additional needs for thermal energy besides what is required for environmental heating. For example, industrial processes use thermal energy to transform materials into other useful shapes or substances, or to initiate or sustain chemical reactions that yield valuable products. Exemplary commercial processes using heat include, without limitation, operations such as metalworking, glassblowing, soldering, drying, baking, hardening, thermosetting, and further including the multitude of heat-requiring reactions in industrial chemistry. In these settings, too, thermal energy is typically provided by conventional processes employing fossil fuel combustion, resulting in the substantial production of carbon dioxide. Industrial heat requirements, including cement production, steel production, and chemical production, are responsible for about 10% of all global greenhouse gas emissions, greater than that of cars and airplanes combined.
The Haber-Bosch process exemplifies a crucial industrial process that requires considerable thermal energy and that produces substantial CO2. The Haber-Bosch process for ammonia formation has revolutionized agriculture over the past century, allowing unreactive diatomic nitrogen to be transformed into a major feedstock for fertilizer synthesis. While the forward reaction of the Haber-Bosch process is exothermic (N2+3H2→2NH3, ΔH°=−91.8 kJ/mol), it needs to be carried out under high-temperature and high-pressure conditions, including temperatures between 400-600° C. Thus, to produce the conditions required for Haber-Bosch reactions, considerable thermal energy is required, which is mainly produced directly or indirectly by combustion of fossil fuels. It is estimated that the Haber-Bosch process worldwide consumes about 2% of the world's total energy production, uses about 2% of the world's natural gas output, and emits 300 million metric tons of CO2 annually: about 1.87 tons of CO2 is released per ton of ammonia produced.
With increasing awareness of the environmental consequences of greenhouse gas emissions, there is a recognized need for alternatives for generating thermal energy for residential and industrial heating purposes that avoid or minimize the production of CO2. There is a further need for convenient and modular systems to produce thermal energy and heat that avoid the complexities, capital expenditures, and logistics of fossil-fuel-based sources of such energy and heat. Advantageously, such systems should be economical and efficient to use, and adaptable to a variety of settings.
The present invention relates to the discovery that apparatuses containing carbon matrices can be used to produce reactant chemicals useful as fuels and chemical feedstocks. The processes of the invention include the application of electromagnetic radiation, directly and/or indirectly, to gases, nano-porous carbon, or compositions and combinations thereof, thereby pre-treating the gas, and exposing a carbon matrix to pre-treated gas in an apparatus of the invention and recovering those reactant chemicals useful as fuels and chemical feedstocks produced therein.
The invention relates to apparatuses for instantiating materials, and processes for using such apparatuses. The invention includes processes comprising the steps of contacting a bed comprising nanoporous carbon with an activated gas while applying electromagnetic radiation to the nanoporous carbon for a time sufficient to cause instantiation of the fuel substance or feedstock substance and collecting the fuel substance or feedstock substance. The invention further relates to the fuel substance or feedstock substance produced by the process.
More specifically, the invention includes a process of instantiating a chemical reactant within a nanoporous carbon powder comprising the steps of:
In one embodiment, the RA coil surrounds a nanoporous carbon bed to establish a harmonic electromagnetic resonance in ultramicropores of the nanoporous carbon powder. The feed gas composition can be, for example, air, oxygen, hydrogen, helium, nitrogen, neon, argon, krypton, xenon, carbon monoxide, carbon dioxide or mixtures thereof, preferably nitrogen or air. Preferably, the nanoporous carbon powder comprises graphene having at least 99.9% wt. carbon (metals basis), a mass mean diameter between 1 μm and 5 mm, and an ultramicropore surface area between about 100 and 3000 m2/g. More specifically, the invention includes a reactor assembly comprising:

The nanoporous carbon powder is preferably characterized by acid conditioning, wherein the acid is selected from the group consisting, without limitation, of HCl, HF, HBr, HI, sulfuric acid, phosphoric acid, carbonic acid, and nitric acid, and a residual water content of less than that achieved upon exposure to a relative humidity (RH) of less than 40% RH at room temperature. In a preferred embodiment, the process contemplates degassing the nanoporous carbon powder prior to the process.
As will be described in more detail below, the reactor assembly can include a plurality of devices that can impart electromagnetic fields, including x-ray sources, coils, lasers and lamps or lights, including pencil lamps, short wave and long wave lamps. The wavelengths generated by each device (e.g., lamps or lasers) can be independently selected.

For example, a first RA coil comprises a copper wire winding, a second RA coil comprises a braiding of copper wire and silver wire, and a third RA coil is a platinum wire winding, and each RA coil is configured to create a magnetic field and wherein each power supply independently provides AC and/or DC current.

Preferably each pair of lamps is equidistantly spaced around the circumference of the reactor chamber.
As will be described in more detail below, the reactor assembly further comprises an electromagnetic embedding enclosure (E/MEE or EMEE), as defined more specifically below. The E/MEE is typically located along a gas line upstream of the reactor assembly gas inlet. Typically, an electromagnetic embedding enclosure located upstream of the gas inlet comprises:
Typically, a CPU independently controls powering each E/MEE pencil lamp and a rotation position of each E/MEE pencil lamp. It is to be understood that the term “independently” is not meant to be absolute but is used to optimize results. Rather, controlling each RA coil, lamp and/or laser (each a device) such that it is powered (or rotated) at the same time or at a time specified before and/or after another device is meant to be “independently” controlled. Thus, assigning two or more devices to a power supply and control unit in series is contemplated by the term. The term is intended to exclude simply powering (or rotating) all devices simultaneously.
As will be described in more detail below, the E/MEE housing can be typically closed and opaque, the internal gas line can be transparent and external gas line in fluid connection with the housing outlet and gas inlet can be opaque. Typically, the internal gas line is between 50 cm and 5 meters or more and has a diameter between 2 mm and 25 cm or more.

Each E/MEE pencil lamp can be independently placed such that its longitudinal axis is (i) parallel to the internal gas line, (ii) disposed radially in a vertical plane to the internal gas line, or (iii) perpendicular to the plane created along the longitudinal axis of the internal gas line or along the vertical axis of the internal gas line. Each E/MEE pencil lamp can be independently affixed to one or more pivots that permit rotation, such as, between about 0 and 360 degrees (such as, between 0 and 90 degrees, between 0 and 180 degrees, between 0 and 270 degrees and any angle there between) with respect to the x, y, and/or z axis wherein (i) the x-axis is defined as the axis parallel to the gas line and its vertical plane, (ii) the y-axis defining the axis perpendicular to the gas line and parallel to its horizontal plane, and (iii) the z-axis is defined as the axis perpendicular to the gas line and parallel to its vertical plane.
As will be described in more detail below, at least one E/MEE pencil lamp can be a neon lamp, at least one E/MEE pencil lamp can be a krypton lamp, and at least one E/MEE pencil lamp can be an argon lamp. It can be desirable to match, or pair, one or more E/MEE pencil lamps with one or more (e.g., a pair) of RA lamps. Accordingly, at least one pair of RA pencil lamps can be selected from the group consisting of a neon lamp, a krypton lamp, and an argon lamp.

The invention relates to methods of instantiating fuels in nanoporous carbon powders. As used herein, the term “fuel” refers to a chemical substance that reacts with other chemical substances (i.e., a chemical reactant) to release thermal energy. Chemical reactants produced by the methods and apparatuses disclosed herein can be formed as fluids (preferably gases) solids, or other states of matter.
The invention involves the production of a chemical reactant useful as a fuel substance using methods comprising the steps of contacting a bed comprising a nanoporous carbon powder with a feed gas composition, and optionally an electromagnetically activated gas, while applying electromagnetic radiation to the nanoporous carbon powder for a time sufficient to cause instantiation within and/or from carbon nanopores. The process results in a product composition comprising a chemical reactant substantially distinct from the feed gas composition. The processes of the invention have broad applicability in producing chemical reactants useful as fuels. Such fuels can be utilized for producing thermal energy, which in turn can be used for producing heat.
The invention relates to the discovery that carbon matrices can be used to instantiate, or filter, or isolate, or extract, or nucleate, a variety of substances, for example producing nano-deposits, nanostructures, nanowires and nuggets comprising metals or non-metals, by employing processes that include the application of electromagnetic radiation, directly and/or indirectly, to gases, nano-porous carbon, or compositions and combinations thereof, thereby pre-treating these materials, and thereafter exposing a carbon matrix to pre-treated gas in an apparatus to cause metal or non-metal instantiation, nucleation, growth and/or deposition within the carbon matrix.
In more detail, the invention relates to methods of instantiating chemical substances in any form, whether fluid (preferably gaseous), solid, or other. In embodiments, the invention produces metals and non-metals in nanoporous carbon matrices, through processes comprising the steps of contacting a bed comprising nanoporous carbon with an activated gas while applying electromagnetic radiation to the nanoporous carbon for a time sufficient to cause instantiation, including but not limited to nucleation, growth deposition and/or agglomeration, of elemental metal or non-metal nanoparticles within and/or from carbon nanopores and nano-pore networks and matrices. Such processes result in nanoporous carbon compositions or matrices characterized by elemental metals and/or non-metals deposited within carbon nanopores and agglomerated elemental nanoparticles, creating elemental metal nuggets, nanowires and other macrostructures that can be easily separated from the nanoporous carbon. In embodiments, these processes can produce elemental metal composition and macrostructures; in embodiments, the nanoporous carbon composition can also comprise non-metal nanostructures and/or macrostructures. In embodiments, the processes can instantiate, or filter, or isolate, or extract, or nucleate materials containing carbon, oxygen, nitrogen, sulfur, phosphorous, selenium, hydrogen, and/or halides (e.g., F, Cl, Br and I). Nanoporous carbon compositions further comprising metal oxides, nitrides, and sulfides such as copper oxide, molybdenum sulfide, aluminum nitride have been identified. Therefore, small inorganic molecules or compounds (e.g., molecules comprising 2, 3, 4, 5, 6, 7, 8, 9 or 10 or 25 atoms) can be instantiated, or filtered, or isolated, or extracted, or nucleated, using the processes disclosed herein. Examples of such small molecules include carbides, oxides, nitrides, sulfides, phosphides, halides, carbonyls, hydroxides, hydrates including water, clathrates, clathrate hydrates, and metal organic frameworks. In embodiments, the processes disclosed herein produce small molecules or other materials useful as fuels. In embodiments, such fuels comprise a fluid (preferably gaseous) selected from the group consisting of hydrogen (H2), carbon (C), carbon monoxide (CO), ammonia (NH3), a substituted or unsubstituted hydrocarbon, a hydrocarbon derivative, and a carbohydrate. In embodiments, the chemical reactant comprises a substituted or unsubstituted hydrocarbon selected from the group consisting of alkanes, cycloalkanes alkenes, alkynes, and substituted or unsubstituted aromatic hydrocarbons, and can comprise a C1-C4 alkane, a C5-C8alkane, a C9-C16 alkane, or an alkane containing 17 or more carbon atoms.
a. Nanoporous Carbon Powders
Nanoporous carbon powders or nanostructued porous carbons can be used in the processes and methods of the invention. Nanoporous carbon powders or nanostructued porous carbons are also referred to herein as “starting material” or “charge material”. The carbon powder preferably provides a surface and porosity (e.g., ultra-microporosity) that enhances metal deposition, including deposit, instantiation, and growth. Preferred carbon powders include activated carbon, engineered carbon, graphite, and graphene. For example, carbon materials that can be used herein include graphene foams, fibers, nanorods, nanotubes, fullerenes, flakes, carbon black, acetylene black, mesophase carbon particles, microbeads and, grains. The term “powder” is intended to define discrete fine, particles or grains. The powder can be dry and flowable or it can be humidified and caked, such as a cake that can be broken apart with agitation. Although powders are preferred, the invention contemplates substituting larger carbon materials, such as bricks and rods including larger porous carbon blocks and materials, for powders in the processes of the invention.
The examples used herein typically describe highly purified forms of carbon, such as >99.995% wt. pure carbon (metals basis). Highly purified forms of carbon are exemplified for proof of principle, quality control and to ensure that the results described herein are not the result of cross-contamination or diffusion within the carbon source. However, it is contemplated that carbon materials of less purity can also be used. Thus, the carbon powder can comprise at least about 95% wt. carbon, such as at least about 96%, 97%, 98% or 99% wt. carbon. In a preferred embodiment, the carbon powder can be at least 99.9%, 99.99% or 99.999% wt. carbon. In each instance, purity can be determined on either an ash basis or on a metal basis. In another preferred embodiment, the carbon powder is a blend of different carbon types and forms. In one embodiment, the carbon bed is comprised of a blend of different nano-engineered porous carbon forms. Carbon powders can comprise dopants.
The carbon powder preferably comprises microparticles. The volume median geometric particle size of preferred carbon powders can be between less than about 1 μm and 5 mm or more. Preferred carbon powders can be between about 1 μm and 500 μm, such as between about 5 μm and 200 μm. Preferred carbon powders used in the exemplification had median diameters between about 7 μm and 13 μm and about 30 μm and 150 μm.
The dispersity of the carbon particle size can improve the quality of the products. It is convenient to use a carbon material that is homogeneous in size or monodisperse. Thus, a preferred carbon is characterized by a polydispersity index of between about 0.5 and 1.5, such as between about 0.6 and 1.4, about 0.7 and 1.3, about 0.8 and 1.2, or between about 0.9 and 1.1. The polydispersity index (or PDI) is the ratio of the mass mean diameter and number average diameter of a particle population. Carbon materials characterized by a bimodal particle size can offer improved gas flow in the reactor.
The carbon powder is preferably porous. The pores, or cavities, residing within the carbon particles can be macropores, micropores, nanopores and/or ultra-micropores. A pore can include defects in electron distribution, compared to graphene, often caused by changes in morphology due to holes, fissures or crevices, corners, edges, swelling, or changes in surface chemistry, such as the addition of chemical moieties or surface groups, etc. For example, variation in the spaces that may arise between layers of carbon sheets, fullerenes or nanotubes are contemplated. It is believed that instantiation preferentially occurs at or within a pore or defect-containing pore and the nature of the surface characteristics can impact instantiation. For example, Micromeritics enhanced pore distribution analysis (e.g., ISO 15901-3) can be used to characterize the carbon. It is preferred that the carbon powder is nanoporous. A “nanoporous carbon powder” is defined herein as a carbon powder characterized by nanopores having a pore dimension (e.g., width or diameter) of less than 100 nm. For example, IUPAC subdivides nanoporous materials as microporous (having pore diameters between 0.2 and 2 nm), mesoporous materials (having pore diameters between 2 and 50 nm) and macroporous materials (having pore diameters greater than 50 nm). Ultramicropores are defined herein as having pore diameters of less than about 1 nm.
Uniformity in pore size and/or geometry is also desirable. For example, ultramicropores in preferred carbon materials (e.g., powders) account for at least about 10% of the total porosity, such as at least about 20%, at least about 30%, at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, or at least about 90%. Preferred carbon materials (e.g., powders) are characterized with a significant number, prevalence, or concentration of ultra-micropores having the same diameter, thereby providing predictable electromagnetic harmonic resonances and/or standing wave forms within the pores, cavities, and gaps. The word “diameter” in this context is not intended to require a spherical geometry of a pore but is intended to embrace a dimension(s) or other characteristic distances between surfaces. Accordingly, preferred carbon materials (e.g., powders) are characterized by a porosity (e.g., nanopores or ultramicropores) of the same diameter account for at least about 10% of the total porosity, such as at least about 20%, at least about 30%, at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, or at least about 90%.
Measuring adsorption isotherm of a material can be useful to characterize the surface area, porosity, e.g., external porosity, of the carbon material. Carbon powders having a surface area between about 1 m2/g and 3000 m2/g are particularly preferred. Carbon powders having an ultramicropore surface area of at least about 50 m2/g, preferably at least about 300 m2/g, at least about 400 m2/g, at least about 500 m2/g or higher are particularly preferred. Activated or engineered carbons, and other quality carbon sources, can be obtained with a surface area specification. Surface area can be independently measured by BET surface adsorption technique.
Surface area correlation with metal deposition was explored in a number of experiments. Classical pore surface area measurements, using Micromeritics BET surface area analytical technique with nitrogen gas at 77K (−196.15° C.) did not reveal a substantial correlation in the deposition of metal elements at ≥5σ confidence level, or probability of coincidence. However, a correlation with ultramicropores (pores having a dimension or diameter of less than 1 nm) was observed. Without being bound by theory, instantiation is believed to be correlated to resonating cavity features of the ultra-micropore and ultramicropore network such as the distance between surfaces or walls. Features of the ultramicropore, can be predicted from ultramicropore diameter as measured by BET, augmented by density function theory (DFT) models, for example. With the aid of machine learning, more precise relationships between ultramicropore size, distribution, turbostratic features, wall separation and diameter and elemental metal nucleation can be established.
Carbon materials and powders can be obtained from numerous commercial providers. MSP-20X and MSC-30 are high surface area alkali activated carbon materials with nominal surface areas of 2,000-2,500 m2/g and >3,000 m2/g and median diameters of 7-13 μm and 60-150 μm respectively (Kansai Coke & Chemicals Co). Norit GSX is a steam-washed activated carbon obtained from Alfa Aesar. The purified carbon forms used in the experimental section all exceed ≥99.998 wt % C (metals basis).
Modifying the surface chemistry of the carbon can also be desirable. For example, improved performance was observed when conditioning the carbon with an acid or base. Contacting the carbon with a dilute acid solution selected from the group consisting of HCl, HF, HBr, HI, sulfuric acid, phosphoric acid, carbonic acid, and nitric acid followed by washing with water (such as deionized water) can be beneficial. The acid is preferably in an amount less than about 30%, less than about 25%, less than about 20% less than about 15%, less than about 10%, or less than about 5%, preferably less than or equal to 1% vol. The preferred acid for an acid wash is an acid having a pKa of less than about 3, such as less than about 2. After washing, it can be beneficial to subject the carbon to a blanket of a gas, such as helium, hydrogen, or mixtures thereof. Alternative gases include, without limitation, carbon monoxide, carbon dioxide, nitrogen, argon, neon, krypton, helium, ammonia, and hydrogen. The carbon can also be exposed to a base, such as KOH before or after an acid treatment.
Controlling residual water content in the carbon which may include moisture can improve performance. For example, the carbon material can be placed in an oven at a temperature of at least about 100° C., preferably at least about 125° C., such as between 125° C. and 300° C. for at least 30 minutes such as about an hour. The oven can be at ambient or negative pressure, such as under a vacuum. Alternatively, the carbon material can be placed in an oven with high vacuum at a temperature of at least about 250° C., preferably at least about 350° C., for at least one hour, such as at least 2, 3, 4, 5, or 6 hours. Alternatively, the carbon material can be placed in an oven with high vacuum at a temperature of at least about 700° C., preferably at least about 850° C., for at least one hour, such as at least 2, 3, 4, 5, or 6 hours. Alternatively, the water or moisture can be removed by vacuum or lyophilization without the application of substantial heat. Preferably, the water, or moisture, level of the carbon is less than about 35%, 30%, 25%, 20%, 15%, 10%, 5%, such as less than about 2%, by weight carbon. In other embodiments, the carbon can be exposed to a specific relative humidity (RH) such as 0.5%, 1%, 2%, 5%, 12% RH or 40% RH or 70% RH or 80% RH or 90% RH, for example, at 22° C.
Pre-treatment of the carbon material can be selected from one or more, including all, the steps of purification, humidification, activation, acidification, washing, hydrogenation, drying, chemistry modification (organic and inorganic), and blending. For example, the carbon material can be reduced, protonated, or oxidized. The order of the steps can be as described, or two or more steps can be conducted in a different order.
For example, MSP-20X was exposed to an alkali (C:KOH at a molar ratio of 1:0.8), activated at 700° C. for 2 hours, washed with acid and then hydrogenated to form MSP-20X Lots 1000 when washed with HCl and 105 when washed with HNO3. MSP-20X was washed with acid and then hydrogenated to form MSP-20X Lots 1012 when washed with HCl and 1013 when washed with HNO3. Activated carbon powder developed for the storage of hydrogen was HCl acid washed, then subjected to HNO3 washing and hydrogenation to form APKI lots 1001 and 1002, as substantially described in Yuan, J. Phys. Chem. B20081124614345-14357. Poly(ether ether ketone) (PEEK, Victrex 450P) and poly(ether imide) (PEI, Ultem® 1000) was supplied by thermally oxidized in static air at 320° C. for 15 h, and carbonized at the temperature range of 550-1100° C. in nitrogen atmosphere, at the carbon yield of 50-60 wt %. These carbons were then activated by the following procedures: (1) grind the carbonized polymer with KOH at KOH/carbon˜ 1/1-1/6 (w/w), in the presence of alcohol, to form a fine paste; (2) heat the paste to 600-850° C. in nitrogen atmosphere for 2 h; (3) wash and rinse with DI water and dry in vacuum oven. PEEK/PEI (50/50 wt) blend was kindly supplied by PoroGen, Inc. Likewise, the acid washing sequence of Lots 1001 and 1002 was reversed to form APKI lots 1003 and 1004. Universal grade, natural graphite, ˜200 mesh was purchased from Alfa Acsar, product number 40799. Graphite lots R and Z were HCl washed and hydrogenated to form R lot 1006 and Z lot 1008, respectively. Alfa Acsar graphite R and Z were nitric acid washed and hydrogenated to form R lot 1007 and Z lot 1009, respectively. MSC-30 (Kansai Coke and Chemicals) was acid washed and then hydrogenated to form MSC30 lots 1010 when washed with HCl and 1011 when washed with HNO3. MSC-30 was exposed to an alkali (C:KOH at a molar ratio of 1:0.8), activated at 700 C for 2 hours, HCl or nitric acid washed and then hydrogenated to form MSC-30 lots 1014 (HCl washed) and 1015 (HNO3 washed), respectively. MSP-20X, MSC-30, Norit GSX and Alfa Acsar R were subjected to purification by MWI, Inc. for MSP-20X Lots 2000 and 2004, MSC-30 Lots 2001, 2006 and 2008, Norit GSX Lots 2005 and 2007, and Alfa Acsar R Lot 2009 respectively. MSP-20X Lot 2000 and MSC-30 2001 were HCl washed and hydrogenated to form MSP-20X Lot 2002 and MSC-30 Lot 2003, respectively. Alfa Acsar R was washed with 1%, 5%, 10%, 15%, 20%, 25%, and 30% HCl (vol.) and then hydrogenated to for R Lot Graphite n % vol HCl, respectively. Purified MSP-20X (Lot 2006) was similarly washed by HCl, nitric acid, HF or H2SO4 to form MSP-20X 1% HCl, MSP-20X 1% HNO3, MSP-20X 0.4% HF, MSP-20X 0.55% H2SO4 (Lot 1044), respectively.

It is preferred to degas the nanoporous carbon powder can be degassed prior to initiating the process. For example, the nanoporous carbon powder can be degassed by subjecting the powder to a vacuum. A range of vacuums can be used, with or without elevated temperatures. It has been found that applying a vacuum of about 10-2 torr to 10-6 torr was sufficient. The powder can be degassed prior to charging the powder into the reactor chamber. Preferably the powder can be degassed after the powder is charged into the reactor chamber. In the examples below, which are non-limiting, the carbon powder is charged into the reactor chamber, placed into the reactor assembly and the entire reactor assembly is subjected to a degassing step by maintaining the reactor assembly under vacuum. The degassing step can be performed at ambient temperature or an elevated temperature. For example, good results were achieved at a temperature of 400° C. Other temperatures can be at least 50° C., such as at least 100° C., at least 150° C., at least 200° C., or at least 300° C. The degassing step can be maintained for at least 30 minutes, such as at least 45 minutes, at least 60 minutes, at least 4 hours, at least 6 hours, at least 12 hours, or at least 24 hours. Degassing the carbon powder ensures that contaminant elements have been removed from the system.
The carbon can be recycled or reused. In recycling the carbon, the carbon can optionally be subjected to an acid wash and/or water removal one or more times. In this embodiment, the carbon can be reused one or more times, such as 2, 3, 4, 5, 10, 15, 20, or about 25 or more times. The carbon can also be replenished in whole or in part. It has been discovered that recycling or reusing the carbon can enhance metal nanostructure yields and adjust nucleation characteristics enabling change in element selectivity and resultant distributions. Thus, an aspect of the invention is to practice the method with recycled nanoporous carbon powder, e.g., a nanoporous carbon powder that has been previously subjected to a method of the invention one or more times.
b. Nanoporous Carbon Compositions
The nanoporous carbon compositions produced by the processes described herein possess several surprising and unique qualities. The nanoporosity of the carbon powder is generally retained during processing and can be confirmed, for example, visually with a scanning electron microscope or modeled by BET analysis. Visual inspection of the powder can identify the presence of elemental nanostructures residing within and surrounding the nanopores. The nanostructures can be elemental metals or non-metals. Visual inspection of the powder can also identify the presence of elemental macrostructures residing within and surrounding the nanopores. The macrostructures can be elemental metals or nonmetals, and can contain interstitial and/or internal carbon, as generally described by Inventor Nagel in U.S. Pat. Nos. 10,889,892 and 10,844,483, each of which is incorporated herein by reference in its entirety. Methods for instantiating gases are described in U.S. Ser. No. 63/241,697 by Inventor Nagel, which is incorporated herein by reference in its entirety.
Typically, the porosity of the nanoporous carbon compositions will be at least about 70% of the porosity attributed to ultramicropores of the nanoporous carbon powder starting, or charge, material and having a total void volume that is about 40% or more of the bulk material volume. The pores, or cavities, residing within the carbon particles can be macropores, micropores, nanopores and/or ultra-micropores. A pore can include defects in electron distribution, compared to graphene, often caused by changes in morphology due to holes, fissures or crevices, edges, corners, swelling, dative bonds, or other changes in surface chemistry, such as the addition of chemical moieties or surface groups, etc. For example, the spaces that may arise between layers of carbon sheets, fullerenes, nanotubes, or intercalated carbon are contemplated. It is believed that instantiation preferentially occurs at or within a pore and the nature of the surface characteristics can impact the deposit. For example, Micromeritics enhanced pore distribution analysis (e.g., ISO 15901-3) can be used to characterize the carbon. It is preferred that the carbon powder is nanoporous. Chemical reactant products or product compositions useful as fuels that are produced by the process can be isolated or harvested from nanoporous carbon compositions.
Conceptually, the apparatus for baseline experimentation can be broken into two primary areas: Gas Processing and Reactor Assembly.
a. Gas Processing:
The gas processing section controls gas composition and flow rate, with the optional embedding of electromagnetic (e.g., light) information or electromagnetic gas pre-treatment to the reactor.
The invention includes an electromagnetic embedding enclosure (E/MEE or EMEE), or apparatus, for processing a gas (feed gas or first gas composition, used interchangeably herein) comprising or consisting of:
It will be understood that spatial terms, such as “above”, “below”, “floor” and “to the side” are relative to a particular specified object or other point of reference. Thus, a lamp, for example, that is positioned “above” a gas line takes its orientation from the gas line as reference point; if the gas line is positioned “above” the floor of the room in which the apparatus is housed, the lamp positioned “above” the gas line is also “above” the floor. A lamp that is positioned “above” the floor does not have a designated position with respect to a gas line that is also positioned “above” the floor unless the lamp's position is also specified with reference to said gas line. In other words, if one were to draw X, Y and Z axes through a particular assembly or apparatus, the terms “above”, “below” and “to the side” is intended to only refer to positions relative to such axes and not as the axes would be drawn relative to the space or room in which the assembly resides.
Feed gases can preferably be research grade or high purity gases, for example, as delivered via one or more gas supplies, such as a compressed gas cylinder. Examples of gases that can be used include, for example and without limitation, air, oxygen, nitrogen, helium, neon, argon, krypton, xenon, ammonium, carbon monoxide, carbon dioxide and mixtures thereof. Preferred gases include nitrogen, helium, argon, carbon monoxide, carbon dioxide and mixtures thereof. Nitrogen, air and helium are preferred. In certain of the examples below, a highly purified nitrogen gas was used. The use of highly purified nitrogen gas facilitated product gas analysis. The feed gas can be added continuously or discontinuously, throughout the process. The gases can be free of metal salts and vaporized metals.
One or more gases (e.g., 2, 3, 4, 5, or more gases) can optionally pass through a gas manifold comprising mass flow meters to produce a feed gas composition, also called the reactor feed gas. The reactor feed gas may then either by-pass an electromagnetic (EM) embedding enclosure (E/MEE) or pass through one or more E/MEEs. The E/MEE exposes the reactor feed gas to various electromagnetic field (EMF) sources. Flow rates, compositions, and residence times can be controlled. The rate of flow of the reactor feed gas can be between 0.01 standard liters per minute (SLPM) and 10 SLPM, or 100 SLPM or more. A constant flow of gas can maintain a purged environment within the reactor. The schematics shown in
Line 102 can be made of a transparent or translucent material (glass is preferred) and/or an opaque or non-translucent material, such as stainless steel or non-translucent plastic (such as TYGON® manufactured by Saint-Gobain Performance Plastics) or a combination thereof. Using an opaque material can reduce or eliminate electromagnetic exposure to the gas as the gas resides within the line. The length of line 102 can be between 50 cm and 5 meters or longer. The inner diameter of line 102 can be between 2 mm and 25 cm or more. Line 102 can be supported on and/or enclosed within a housing or substrate 111, such as one or more plates, with one or more supports 112. For example, substrate 111 can be configured as a plane or floor, pipe, or box. Where the substrate is a box, the box can be characterized by a floor, a ceiling and side walls. The box can be closed to and/or insulated from ambient EM radiation, such as ambient light.
One or more lamps (such as 2, 3, 4, 5, 6, 7, 8, 9, 10 lamps or more) can be configured within the E/MEE. Lamps (numbered individually) are preferably pencil lamps characterized by an elongated tube with a longitudinal axis. The pencil lamps can independently be placed such that their longitudinal axes are (i) parallel to the line 102, (ii) disposed radially in a vertical plane to the line 102, or (iii) perpendicular to the plane created along the longitudinal axis of the line 102 or along the vertical axis of the line 102.
Each lamp can, independently, be fixed in its orientation by a support 112. Each lamp can, independently, be affixed to a pivot 113 to permit rotation from a first position. For example, the lamps can be rotated between about 0 and 360 degrees, such as about 45, 90, 135, 180, 225 or 270 degrees, preferably about 90 degrees relative to a first position. The rotation can be with respect to the x, y, and/or z axis wherein (i) the x-axis is defined as the axis parallel to the gas line and its vertical plane, (ii) the y-axis defining the axis perpendicular to the gas line and parallel to its horizontal plane, and (iii) the z-axis is defined as the axis perpendicular to the gas line and parallel to its vertical plane.
Referring to the specific pencil lamps within an E/MEE, line 102 is configured along the E/MEE with gas flowing from the inlet 101 and exiting at the outlet 110. Lamp 103, a neon lamp, is first and is shown above line 102 oriented to be along the z-axis and perpendicular to line 102, with the tip of the lamp pointed towards line 102. Lamp 109, a krypton lamp, is shown below line 102 oriented to be parallel to the x-axis, with the tip pointing towards the outlet 110. Lamps 104 and 105, a long wave and short-wave lamp, respectively, are shown parallel to line 102 oriented to be along the x-axis with the tips pointing towards the inlet. Lamp 122, an argon lamp, is shown to be below line 102 oriented to be parallel to the x-axis, with the tip pointing towards the inlet 101 at approximately the same distance from the inlet as lamps 104 and 105. Lamp 106, a neon lamp, is downstream at about the midpoint of the E/MEE, is above line 102 with the tip pointing down. Lamp 107, a xenon lamp, is shown downstream of lamp 106 above line 102, parallel to the x axis of line 102 and points toward the outlet 110. Lamp 108, an argon lamp, is below line 102 and the tip is pointing toward line 102 along the z-axis. Optional coil 120 is wrapped around line 102. Each of these lamps can be independently rotated, for example, 90 degrees along any axis. Each lamp is connected to a power supply or power source to turn on or off the power. Each lamp can be independently rotated 1, 2, 3, 4 or more times during the process. For convenience, each lamp is held by a pivot that can be controlled by a central processing unit, such as a computer programmed to rotate the pivot and provide power to each lamp. For the case of describing the experimental procedures, each orientation of each lamp is called “position n” wherein n is 0, 1, 2, 3, 4, or more. As the procedure is conducted, each lamp can be powered for specific periods of time at specific amperage(s) and positioned or repositioned.
In the exemplification described below, the initial bulb position for each lamp is described with a degree. A zero-degree (0°) reference point is taken as the 12 o'clock position on the glass pipe when looking down the gas pipe in the direction of intended gas flow (e.g., when looking at the E/MEE exit). The length of the glass pipe or line is taken as the optical length (e.g., in this instance 39 inches). For example, 6 inches from the end is defined as 6 inches from the optical end of pipe.
The lamps can be placed above, below, or to the side (for example, level with the longitudinal axis or a plane parallel to (above or below) the longitudinal axis), for example, of line 102. The lamps can be independently placed between 5 and 100 cm from the center of the line 102 in the vertical plane, as measured from the tip of the lamp to the center of line 102. One or more lamps can be placed in the same vertical plane along line 102, as illustrated by lamps 122, 104, and 105. Two lamps are in the same vertical plane if they (as defined by the tip or base of the lamp) are the same distance from the inlet 101. Preferably, lamp 105 can be placed in a plurality of (e.g., 2, 3, 4, 5 or more) vertical planes along the length of line 102 within the E/MEE. Further, one or more lamps can be placed in the same horizontal plane above, below or through line 102, as shown with lamps 104 and 105. Two lamps are in the same horizontal plane if they (as defined by the tip or base of the lamp) are the same distance from the center of line 102. Preferably, lamps can be placed in a plurality of (e.g., 2, 3, 4, 5 or more) horizontal planes along the length of line 102 within the E/MEE, as generally illustrated.
It is understood that “pencil lamps,” as used herein, are lamps filled with gases or vapor that emit specific, calibrated wavelengths upon excitation of the vapor. For example, pencil lamps include without limitation argon, neon, xenon, and mercury lamps. For example, without limitation, one or a plurality of lamps can be selected from argon, neon, xenon or mercury or a combination thereof. Preferably, at least one lamp from each of argon, neon, xenon, and mercury are selected. Wavelengths between 150 nm and 1000 nm can be selected. One example of a pencil lamp is a lamp characterized by an elongated tube having a tip and a base.
Long wave and/or short-wave ultraviolet lamps can also be used. Pencil lamps used in the E/MEE were purchased from VWR™ under the name UVP PEN_RAY® rare gas lamps, or Analytik Jena in the case of the UV short wave lamps.
A power supply is operably connected to independently to each lamp, E/MEE coil, and frequency generator. The power supply can be AC and/or DC.
The E/MEE can be open or enclosed. Where the E/MEE is enclosed, the enclosure is typically opaque and protects the gas from ambient light. Without limitation, the enclosure can be made of a plastic or resin or metal. It can be rectangular or cylindrical. Preferably, the enclosure is characterized by a floor support.
In baseline experimentation the feed gas can by-pass the E/MEE section and are fed directly to the reactor assembly. The energy levels and frequencies provided by the EM sources can vary.
The coil 407 is preferably made of conducting material and is connected to a power supply and, optionally, a frequency generator. The coil can comprise copper, aluminum, platinum, silver, rhodium, palladium or other metals or alloys (including braidings, platings and coatings) and can optionally be covered with an insulating coating, such as glyptal. It can be advantageous to use a braid of 1, 2, 3 or more metal wires. The coil can be manufactured from wire typically used in an induction coil and can vary in size and the number of turns. For example, the coil can comprise, 3, 4, 5, 6, 7, 8, 9, 10 or more turns. The inner diameter of the coil can be between 2 cm and 6 cm or more and preferably snugly fits the line 410. An x-ray source 429 can included in the E/MEE. For example, the x-ray source can be directed at line 410 along the line between the inlet 401 and outlet 409. For example, it can be advantageous to direct the x-ray source at coil 407, where present.
b. Reactor Assembly (RA):
The invention further relates to a reactor assembly comprising:
The invention also includes a reactor assembly comprising:
As previously described, the terms “above,” “floor” and “ceiling” are intended to describe relational spatial features. “Floors” and “ceilings” are typically opposing sides of a space or volume where the head space is adjacent to the “ceiling” and distal to the “floor,” irrespective of the relational geometry to the room or space in which the apparatus resides. In other words, a “ceiling” represents a boundary wall or plane in an assembly confining a space or volume (generally understood as the “top” boundary of such space or volume), while the “floor” represents a boundary wall or plane opposite the ceiling in the same assembly confining the same space or volume (generally understood as the “bottom” boundary of such space or volume). Rotating the assembly on an axis by, for example, 45, 90 or 180 degrees, for example, does not change the relative position of the two planes or assemblies to each other, and such a rotated assembly can still include references to the ceiling or a floor structure thereof as these structures were identified in the assembly prior to such rotation.
The invention also includes a reactor assembly comprising:
As shown in
Each conducting coil 208 (or coils) can generate inductive heat and, optionally, a magnetic field. Standard induction coils or reverse field induction coils (coils that have a lower and upper sections connected through an extended arm that allows the sections to be wound in opposite directions, thereby producing opposing magnetic fields) are preferred. The coil 208 can be water-cooled via a heat exchanger. The coil can be connected to a power flange 210, which can be water cooled as well and in turn can connect to a power supply, such as an Ambrell 10 kW 150-400 kHz power supply. In baseline experimentation a standard coil was used with simple copper windings. The windings can form a coil 208 such that the connection to the power supply is at opposite ends of the coil
Referring to
Coils can be manufactured from electrically conducting materials, such as, without limitation, copper, platinum, silver, rhodium, palladium and, wire braids or coated wires of two or more materials. Each coil in a grouping may be made of the same material or different. For example, a grouping can be made such that each coil is made of a different material. For example, a braiding of copper wire and silver wire can be used. Silver plated copper wire can be used. A first RA coil can be made of a copper winding. A second RA coil can be a copper/silver braid. A third RA coil can be a platinum wire winding. An RA coil can be configured to create a magnetic field and wherein each power supply independently provides AC and/or DC current. Any one or all RA coils can be optionally lacquered.
The coils are preferably circular in geometry. However, other geometries, such as, without limitation, rounded shapes, ellipses and ovoids can be used. The wire diameter can be between about 0.05 mm (>about 40 gauge) and about 15 mm (about 0000 gauge) or more. For example, the wire diameter can be between about 0.08 mm (about 40 gauge) and about 0.8 mm (about 20 gauge) wire. Excellent results have been obtained using 0.13 mm (36 gauge) wire. Coils can be wire windings (e.g., the wire can be wound in 1, 2, 3, 4, 5, 6, 7, 8, 9, 20, or more turns or can be a single turn. In this context, a “wire” can also be considered a band where the width of the material is greater than the depth.
The inner diameter (or dimension(s) where the coil is not a circle) of each coil can be the same or different and can be between 2 and 200 cm.
Coils 208 can independently be connected to one or more power supplies, such as an AC or DC power supply or combination thereof. For example, an AC current can be supplied to alternating (1, 3, and 5, for example) or adjacent coils (1, 2 and/or 4, 5, for example) while DC current is supplied to the remaining coils. Current can be provided (independently) in a frequency, such as in a patterned frequency, e.g., triangle, square or sine pattern or combination thereof. The frequency supplied to each coil can be the same or different and between 0 to 50 MHz or higher. While the coils 208 can generate and transfer thermal energy, or heat, to the reactor feed gas they are predominantly used to create a magnetic field.
The power supply can be an AC and/or DC power supply or combination thereof. Current can be provided (independently) in a frequency, such as in a patterned frequency, e.g., triangle, square or sine pattern or combination thereof. The frequency supplied to each coil can be the same or different and between 0 to 50 MHz or higher, such as between 1 Hz to 50 Mhz.
As described above, the RA coils typically surround the reactor chamber and/or reactor head space. For example, a first RA coil can be aligned with the first (or bottom) frit. A second RA coil can be aligned with the reactor chamber or nanoporous carbon bed. A third RA coil can be aligned with the second (or top) frit. Where present, a fourth RA coil can be disposed between the first RA and the second RA coil. When present, a fifth RA coil can be disposed between the second RA coil and third RA coil. When two or more reactor chambers, or nanoporous carbon beds are present, it can be desirable to add additional RA coils, also aligned with a second or additional reactor chambers or nanoporous carbon beds. Additional RA coils can be added to align with additional frits when present.
The RA coils can typically be supported in a support or stator to maintain a fixed distance between each coil. The support, when present, can be transparent. In one embodiment, the RA coils can be configured in a cartridge that can be removed or moved.
The RA coils can, additionally or alternatively, be aligned with the reactor headspace. The reactor headspace can typically be a volume above the second, or top, frit. It is understood that where the reactor assembly is positioned horizontally (or at some other angle than vertical), the geometry of the spaces is maintained, albeit rotated. The reactor headspace can typically be an enclosed volume. For example, the reactor assembly can be inserted into a closed ended transparent (e.g., glass) tube, vial, or bottle. The reactor assembly can be movably engaged with the RA coils (or boundary), thereby permitting each RA coil to align to a different element within the reactor assembly. For example, the first RA coil can be realigned with the reactor chamber.
Referring to
The reactor body 202 is generally contained within a housing, e.g., closed end tube, 207 and frits 203, which function to contain the charge material 204. It can be advantageous to use a reactor within a translucent or transparent housing, such as quartz or other materials characterized by a high melting point. The volume of the reactor bed can be fixed or adjustable. For example, the reactor bed can contain about 1 gram, or less of starting material, between about 1 g to 1 kg of starting material or more. Where the reactor assembly comprises two or more reactor chambers, the reactor chambers are preferably directly or indirectly stacked, preferably having a common central axis, and can be separated by one or two frits.
The reactor body 202 can, for example and without limitation, be made of a thermally conductive material, such as graphite, copper, aluminum, nickel, molybdenum, platinum, iridium, cobalt, or niobium, or non-thermally conducting material, such as quartz, plastic (e.g., acrylic), or combinations thereof. An optional cup 206 capped with cap 205 can be advantageous. The cup and cap material can be independently selected. For example, a graphite cup can be combined with a graphite cap, which is the selection for the examples below. A copper cup can be combined with a graphite cap. A graphite cup can be combined with a copper cap. A copper cup can be combined with a copper cap and so on.
The reactor assembly can also receive the gas line through the entrance, or inlet, 201 and to provide an exhaust through an exit, or outlet, 209, optionally controlled by valves. A head space defined by a closed end tube 207 can be configured above the reactor body. The reactor body is preferably made of graphite, copper, or other inorganic rigid material. The gas line is preferably made of an inert tubing, such as glass, acrylic, polyurethane, plexiglass, silicone, stainless steel, and the like can also be used. Tubing can, optionally, be flexible or rigid, translucent or opaque. The inlet is generally below the charge material. The outlet can be below, above, or both.
Frits 203 used to define the chamber containing the charge material are also shown. The frits can be made of a porous material which permits gas flow. The frits will preferably have a maximum pore size that is smaller than the particle size of the starting material. Pore sizes of between 2 and 50 microns, preferably between 4 and 15 microns can be used. The thickness of the frits can range satisfactorily between approximately 1 and 10 mm or more. The frits are preferably made of an inert material, such as silica or quartz. Porous frits from Technical Glass Products (Painesville Tp., Ohio) are satisfactory. On the examples below, fused quartz #3 porous frits (QPD10-3) with a pore size between 4 and 15 microns and a thickness of 2-3 microns and fused quartz frits with a pore size between 14 and 40 microns (QPD10-3) were used. The purity of the frits exemplified herein was very high, 99.99% wt, to ensure that the results obtained cannot be dismissed as the result of contamination. Frits of lower purity and quality can also be used. The diameter of the porous frit is preferably selected to permit a snug fit within the reactor interior, or cup. That is, the diameter of the porous frit is approximately the same as the inner diameter of the reactor or cup, if present.
The reactor assembly may be augmented with additional forms of electromagnetic radiation, such as light.
The RA lamps, e.g., the pencil lamps proximal to the reactor body, can be matched, or paired, to one or more E/MEE lamps, e.g., the pencil lamps residing within the E/MEE housing and proximal to the gas line. For example, where an E/MEE pencil lamp is a neon lamp, a pair of RA lamps can be neon pencil lamps. Additionally, where an E/MEE pencil lamp is a neon lamp, a pair of RA lamps can be neon pencil lamps. Such matched lamps can emit light characterized by substantially the same wavelength. This can be conveniently achieved by using lamps from the same manufacturer with the same specifications.
The reactor can be in a closed or open housing 415 and can be supported therein by reactor supports. The reactor feed gas is directed to the reactor inlet frit, or bottom frit, directed through the starting material contained within the housing 415 and exits the reactor at the reactor exit frit, or top frit. The reactor feed gas can then be exhausted or recycled, optionally returning to the E/MEE for further treatment.
The reactor can further comprise an x-ray source 211 (

The residence time of the starting material within the reactor is effective to instantiate, or filter, or isolate, or extract, or nucleate, product into the starting material and can be between 0 and 15 minutes or more.
Preferred reactors used in the methods of the invention are shown in the table below.
The invention further relates to methods of instantiating materials in nanoporous carbon powders. It has been surprisingly found that light elements, such as hydrogen, oxygen, helium, and the like are instantiated, or filtered, or isolated, or extracted, or nucleated. Instantiating is defined herein to include the nucleation and assembly of atoms within carbon structures, particularly, ultramicropores, and it includes without limitation processes such as filtering, or isolating, or extracting, or nucleating such atoms. Without being bound by theory, it is believed instantiation is related to, inter alia, degrees of freedom of the electromagnetic field as expressed by quantum field theory. By exposing a gas to harmonic resonances, or harmonics, of electromagnetic radiation within one or more ultramicropores, vacuum energy density is accessed and allows for the nucleation and assembly of atoms. Electromagnetic energy that is within the frequencies of light, x-rays, and magnetic fields subjected to frequency generators can enhance the formation and maintenance of such harmonics. Modifying the boundaries of the system, by selecting the reactor materials and adding a foil layer can also enhance the harmonics.
In particular, the invention includes processes of producing, or instantiating, nanoporous carbon compositions comprising the steps of:
The invention includes a process for producing a chemical reactant comprising the steps of:
The term “harmonic patterning” is defined herein as oscillating between two or more energy levels (or states) a plurality of times. The energy states can be characterized as a first, or high, energy level and a second, or lower, energy level. The rates of initiating the first energy level, obtaining the second energy level and re-establishing the first energy level can be the same or different. Each rate can be defined in terms of time, such as over 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more seconds. Each energy level can be held for a period of time, such as 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more seconds. Harmonic patterning is continued until instantiation is achieved.
Where two more electromagnetic radiation sources are present (e.g., coils, x-ray source, lasers, and/or lamps), each can be subjected to harmonic patterning and the patterning can occur independently, simultaneously or sequentially.
The process further comprises independently powering any additional electromagnetic radiation source, as described above in the E/MEE apparatus or reactor assembly. For example, the process further comprises the step(s) of powering RA frequency generator(s) connected to one or more RA coils, one or more lamps or lasers, x-ray sources, induction coils, E/MEE coils, and the like substantially as described above.
c. Use Cases for Chemical Reactants
Methods and and apparatus for producing chemical reactants in accordance with these inventions can be appreciated in more detail by reference to the following description and Figures.
i. General Use Cases
In general terms, a reactor assembly (RA) as disclosed herein can interface with a system within which a chemical reaction can take place, which chemical reaction utilizes the chemical reactant(s) produced by the RA. Such a system for utilizing chemical reactants to support chemical reactions can be termed a “reaction system,” (RS) and it can comprise an apparatus or enclosure within which a chemical reaction takes place. The term “reaction system” is not limited to closed vessels for reactions, since it is understood that certain chemical reactions such as flame combustion do not require a closed system, but can occur in “the open.” As described previously, a RA produces a chemical reactant that can be supplied to a RS; one or more RAs can produce one or more chemical reactants, to be used by one or more RSs.
In the exemplary embodiment, shown schematically in
Depending on the particular embodiment, the RS 10 acting as a “fuel-sink” can be, without limitation: (i) any fuel-consuming apparatus, such as a thermal apparatus that converts fuel to heat, alone or in combination with (ii) an engine that converts fuel to mechanical energy; (iii) a fuel-cell that converts fuel to electricity; (iv) any other apparatus that consumes a chemical substance; (v) any fuel-storage facility such as a tank or other container that stores the fuel; (vi) any reactant-transformation process that uses a chemical reactant as a feedstock or precursor in the production of other chemicals or materials, or any combination of the foregoing.
As depicted in
Systems incorporating one or more RAs in communication with one or more RSs can include one or more fuel consumers, one or more fuel retainers and one or more fuel transformers. For example, RAs 12 and/or 14 can be coupled to a storage facility apparatus whereby the chemical substance(s) (e.g., a fuel) can be retained for use elsewhere or later; or can be moved through a conduit for other processing such as being used as a feedstock or precursor to the production of other chemicals.
In embodiments, a plurality of RAs can be harnessed to form an integrated system delivering appropriate quantities of chemical reactants to a RS in order to achieve a desired reaction. Such a system is illustrated in
In the depicted example, “M” RAs(s) 900 (where M is zero or any positive integer) can be configured to assemble a second chemical substance, such as a chemical reactant (e.g., an oxidant) appropriate for the fuel sink and deliver the chemical substance to the fuel sink, i.e., RS 10. It is understood that the RA bank or set 900(1)-900(M) is optional, to be used in systems where a second chemical substance is to be provided to the RS in addition to the chemical substance produced by the RA bank or set 500(1)-500(n). Any number of additional RAs or banks or sets of RAs can be provided to supply any number of and quantity of chemical substances individually, alternately, simultaneously or in any desired mixtures or ratios, to RS 10.
The chemical substances produced by RAs 500, 900 are supplied to RS 10 via one or more conduits 600, 600′. Thus, as material moves between points it is said to move through a “conduit”. Examples of such materials include without limitation: hydrogen, ammonia (NH3), hydrocarbons, alcohols (as fuels); oxygen, ozone, hydrogen peroxide (H2O2), (as oxidants); helium, xenon, argon, krypton, (as elements to moderate or buffer the reaction); nitrogen, other gases, fuels, oxidizing agents, boron, calcium, aluminum, and any other elements or compounds used within the system. Depending on an implementation's design and engineering constraints, a “conduit” may vary from being a trivial, almost abstract, connection to a complicated path in which a number of operations are performed, sometimes conditionally, on the subject material. Such operations may include, for example and without limitation, being: pumped, collected, combined, e.g., combined with the output of other conduits or sources, pressurized, compressed, liquefied, solidified, stored, packaged, transported, hauled, unpackaged, repackaged, gasified, uncompressed, depressurized, filtered, mixed, agitated, centrifuged, shaken, oscillated, stirred, vibrated, gated, shunted, injected, diverted, merged, blown, aerated, propelled, spun, blended, dissolved, extracted, sensed, tested, humidified, dehumidified, monitored, measured, regulated, accumulated, cooled, heated, or otherwise processed. Such operations may involve the use of components including for example and without limitation: pumps, sensors, gates, shunts, injectors, valves, baffles, pipes, splitters, plumbing, relays, filters, controls, accumulators, tanks, containers, reservoirs, fans, blowers, propellers, impellors, aerators, agitators, oscillators, vibrators, shakers, stirrers, centrifuges, pressurizers, humidifiers, dehumidifiers, compressors, refrigerators, blenders, mixers, vats, dissolvers, extractors, coolers, heaters, gasifiers, liquefiers, and sensors and controls for flow, humidity, concentration, density, purity, particle size, particle diameter, particle surface area, particle weight, viscosity, temperature, volume, and pressure, as well as other sensors and controls and processing equipment. Each operation may be performed zero or more times, sometimes simultaneously, and the order in which they are performed (and whether they are appropriate or necessary) depends on a particular implementation's design, tradeoffs, and constraints. Conduits may also be used to route power and signal cables. A conduit 600, 600′ may thus without limitation comprise a single pipe or other structure capable of conducting fluids (preferably gases), a conveyor for conducting powders or solids, a blower system for moving powders or gas. a manifold that couples the outputs of multiple RAs 500 together as a bank or set of RAs, a mixer that mixes the outputs of multiple RAs together, or any other suitable structure for conveying outputs of RAs 500 to RS 10. As shown in
The processor 100 may also send signals over bus 300/300′ to control aspects of the state and operation of each RA 500, 900 such as flow control, output rate, and any other relevant state, parameter or characteristic. As shown in
In some embodiments, battery 200 provides ancillary power to various components in addition to processor 100. Battery 200 is shown external to the reactor, although in many embodiments it can be internal to the reactor, such as if the RS is implemented as or includes a fuel cell, an alternator/generator, or possesses other electrical power generation capabilities, if present, to receive and maintain charge. In some embodiments, battery 200 can be supplemented or replaced by other power sources such as solar panels, fuel cells, generators, alternators, or any external power sources, etc. In embodiments, the system depicted in
In an embodiment, an operator (and/or the computer processor 100) activates the system by setting an ignition switch (not shown) to “on”. Referring to
In an embodiment, the RAs 500 are activated to instantiate, or filter, or isolate, or extract, or nucleate, a chemical reactant useful as a fuel material, which can be atoms or molecules, such as hydrogen (H2). The chemical reactant produced by the RAs 500 is/are collected by the conduit 600, optionally purified or separated, which can further process it in various ways (denoted by the chemical processor 670) as appropriate before it is delivered to the RS 10 through an intake port 750. The chemical processor 670 can include various aspects of conduit(s) 600 that may exist and be attached to processor 100 and battery 200. Similarly, RAs 900 in one embodiment can instantiate, or filter, or isolate, or extract, or nucleate, a chemical reactant useful as an oxidizing agent which can be atoms or molecules, such as oxygen (O2). The chemical reactant emitted by the RAs 900 (1-M) (if present) is/are collected by the conduit 600′ which can process it in various ways (denoted by the chemical processor 670′) as appropriate before it is delivered to the RS 10 through its reactant intake 750′.
After an operation reacting the different chemical reactants takes place in the RS 10 with satisfactory completion, the computer 100 can conduct a proper close-down for the RAs 500, 900, conduits 600, 600′, processors 670, 670′, RS 10, battery 200, any other integrated equipment, and for itself 100. The satisfactory completion of the intended chemical reaction in the RS 10 can be determined in various ways depending on the particular specific embodiment. In certain embodiments, the completion can be signaled by the operator setting an ignition switch (not shown) to “off,” or can be signaled via some computer interaction or artificial intelligence decision, or can be signaled by any sensor, detector, monitor, or probe interior to, or exterior to RS which may be available to the processor, or can be signaled by parameters pertaining to the RS itself, such as the passage of time or the generation of heat or other energy, or can be signaled by the status of a storage unit or other non-reactive fuel sink, such as a storage tank reaching a full state.
The Figures that follow depict other use cases that exemplify the principles for the RAs and RSs as disclosed herein.
ii. Use Cases Involving Gaseous Reaction Products
In embodiments, the chemical reactant produced by the methods disclosed herein can be in gaseous form, which can be entrained within gaseous product compositions, or “product gas.” The invention particularly relates to the identification and collection of a product gas produced by the methods. The product gas can be collected from the process in a continuous, semi-continuous or batch manner. The product gas typically comprises the feed gas or feed gas composition, as discussed above, and the chemical reactant in gaseous form. The chemical reactant in gaseous form is distinct from the feed gas, and preferably contains one or more gases not present in the feed gas. For example, where the feed gas is pure nitrogen (e.g., a gas comprising at least 99% vol nitrogen, such as at least 99.9% vol nitrogen), the product gas will contain one or more other materials (e.g., elements or molecules that exist in gas form under ambient conditions). The feed gas can also include air. In embodiments, the product gas comprises hydrogen and an additional gas such as helium, water, neon, nitrogen, carbon monoxide, oxygen, argon, carbon dioxide, fluorocarbons, ammonia, krypton, xenon, methane and other hydrocarbons or organics and mixtures thereof. For avoidance of doubt, the term “product gas,” as used herein, is understood to be compositionally distinct different from the term “feed gas,” and the term “product gas” explicitly excludes air.
In embodiments, the product gas comprises one or more chemical reactants in gaseous form, and can include, without limitation chemical reactants or additional gases including helium, water, neon, nitrogen, carbon monoxide, oxygen, argon, carbon dioxide, fluorocarbons, ammonia, krypton, xenon, methane and other hydrocarbons or organics and mixtures thereof, provided that such chemical reactants or additional gases are not components of the feed gas or feed gas composition. The invention permits the manufacture of green gas, such as product gas that has less than 0.5% vol CO2, such as less than 100 ppm CO2. Preferred product gases comprise at least about 1% vol (preferably at least about 4% vol) of a chemical reactant. Product gases can further comprise neon, helium, argon, and combinations thereof. Typically, the product gas will further comprise the components found in the feed gas (e.g., nitrogen or air), however, in concentrations distinct therefrom.
The invention permits the manufacture of green gas, such as product gas that has less than 0.5% vol CO2, such as less than 100 ppm CO2. In an embodiment, hydrogen can be isolated from, or purified, the product gas, thereby producing a high concentration hydrogen gas. An example of a purification system utilizing a hydrogen-selective membrane. Examples of suitable materials for membranes include palladium and palladium alloys, and especially thin films of such metals and metal alloys. Palladium alloys are particularly effective, especially palladium with 35 weight % to 45 weight % copper. Another effective alloy is palladium with 2 weight % to 10 weight % gold, such as palladium with 5 weight % gold. Hydrogen-selective membranes can be configured to be a foil. Alternatively or additionally, a pressure swing adsorption system can be used to concentrate hydrogen and remove unwanted gases. Such processes use activated carbon, silica, or zeolites.
iii. Use Cases Involving Fuels Generally
In embodiments, the invention particularly relates to the identification and collection of chemical reactants useful as fuels produced by the disclosed methods. In embodiments, the methods and apparatus disclosed above can produce chemical reactants such as fuel substances and/or reductants including, but not limited to, the many and varied substances containing hydrogen, carbon, nitrogen, oxygen, calcium, sodium, potassium, phosphorus, sulfur, or other materials, such as other oxidizable materials, such as, by way of example but not limited to: hydrogen (H2), carbon (C), carbon monoxide (CO); ammonia (NH3); unsaturated aliphatic hydrocarbons, such as alkynes and alkenes (including olefins); saturated hydrocarbons (e.g., alkanes, paraffins); cyclic and polycyclic hydrocarbons including aromatic compounds; heterocyclic compounds; and a vast collection of other organic compounds, of which a small sample includes: alcohols, such as alkanols (such as monohydric (CnH2n+1OH), diols or polyols, unsaturated aliphatic, alicyclic, and other alcohols having various hydroxyl attachments); nitroalkanes such as nitromethane (CH3NO2); carbohydrates; and the like. In embodiments, these fuel substances can include substituted or unsubstituted alkanes or paraffins of various sizes and structures, for example methane (CH4), ethane (C2H6, CH3CH3), propane (C3H8), butane (C4H10); pentane (C5H12), hexane (C6H14), heptane (C7H16), octane (C8H18), C9-C16 alkanes, or heavier molecules can also be used as fuel or for other purposes, such as lubricating oil, wax, or asphalt. In many cases, the methods and apparatuses disclosed herein can directly instantiate, or filter, or isolate, or extract, or nucleate, the chemical substance, the production of which might otherwise require transformation by a chemical reaction or a different source.
While the use of these methods and apparatuses for producing conventional chemical reactants useful as fuels (including but not limited to those disclosed herein) is especially advantageous, these methods and apparatuses also are capable of producing materials not usually considered to be fuels, but which can be economically harnessed in appropriate situations for the energy of their exothermic fuel-like reactions with other chemical substances, such as oxygen and other oxidizing agents described herein. Such atypical fuels produced by these methods and apparatuses include those elements such as calcium, sodium, lithium, and the like, that are so reactive in the natural environment that they are not encountered in their unbound, elemental state. Examples of such atypical fuels include, without limitation, alkali metals: Li (which can react, e.g., with O2, H2O, CO2, N2), Na, K, and the like; alkaline earth metals (Be, Mg, Ca, and the like); and those other elements and compounds that can be involved in exothermic reactions, such as Al, Fe, CaO, and the like, including for example but without limitation, those that can be made to undergo exothermic reactions, such as Al, Fe, CaO. While the reactions involving conventional fuels tend to take place via a redox mechanism using an oxidizing agent such as oxygen, the chemical substances available as fuels are not limited to those that undergo redox reactions. Atypical fuels can produce energy through non-redox mechanisms, for example, a reaction between metal oxide such as CaO, and H2O, and similar reactions.
Chemical reactants produced by the methods and apparatuses disclosed herein can also include oxidants (i.e., oxidizing agents), which can be used to react with reductants or fuels produced by the methods and apparatuses disclosed herein, or which can be isolated to be used for other purposes. The oxidants that can be instantiated, or filtered, or isolated, or extracted, or nucleated, by these methods and apparatuses include without limitation, atomic oxygen and oxygen species, hydrogen peroxide, water (which can exothermically oxidize alkali metals, alkaline earth metals, and the like, and can exothermically react with alkali metal oxides or alkaline earth metal oxides such as CaO), halogen molecules such as F2, Cl2, Br2, and the like, and other reactive metals (e.g., metal oxides) or non-metals.
In embodiments, the invention particularly relates to the identification and collection of chemical reactants useful as fuels produced by the foregoing methods. Fuels or oxidants that react with such fuels can be produced by the methods and apparatuses disclosed herein and can be stored in various containers or other retaining mechanisms for use elsewhere. Such containers or retaining mechanisms (collectively, “retainers”) allow the chemical reactants thus produced to be stored for use elsewhere or at a later time. Retainers can include, without limitation, bags or tanks or bottles (for fluids (preferably gases), caves (for gases), bags, envelopes or boxes (for solids), conduits, or any other vessel or other structure that at least for a discernible period of time (whether short or long), either while in transit or statically, stores a quantity of the chemical reactant.
iv. Use Cases Involving Fuels: Thermal Systems
A number of use cases can be envisioned that employ one or more RAs, as described above, for the production of fuels and/or oxidants to be used in one or more RSs in systems that function to produce heat. As used herein, a RS that effects the reaction between the fuel-reactant produced by the RAs and an oxidant-reactant produced by the RAs; or between the fuel reactant produced by the RAs and an oxidant derived from a conventional oxidant source, for example ambient air, or an oxygen tank, or a pipeline, or a similar conventional source; or between an oxidant produced by the RAs and a fuel reactant derived from a conventional fuel source, such as a tank, a pipeline, or a similar conventional source, is termed a “thermal apparatus.” A thermal device comprises the thermal apparatus and the sets of one or more RAs that produce the fuel or oxidant reactants (or both), and further comprise any sources of fuel or oxidant that do not involve their production by a set of one or more RAs. A thermal system comprises one or more thermal devices, with each thermal device comprising at least one thermal apparatus, as described herein. Such a system, comprising one or more RAs and one or more RSs to produce thermal energy and to transfer it to an external body or environment, is termed a “thermal system.” A thermal system comprises mechanisms or subsystems for heat transfer: the process of transferring the thermal energy to the external body or environment is termed “heat transfer”; the external body or environment to which the thermal energy is transferred is termed the “heat recipient.”
As used herein, the term “thermal system” includes, without limitation, those devices, apparatuses, appliances, or equipment employing a thermal apparatus for which the production of thermal energy is a goal or by-product. In other words, the primary goal for a thermal system is the production of heat (i.e., the transfer of thermal energy from one body to another) as distinguished from having a primary goal of producing mechanical energy. This distinguishes a thermal system in accordance with the principles of the invention from an engine or other mechanism that leverages the principles of the invention to produce thermal energy, but uses such thermal energy for the purposes of performing work. For example, while a locomotive can include a boiler that burns coal to heat water, the primary objective of the locomotive boiler is not the production of the thermal energy per se, but rather the transfer of heat into the water to turn it into steam, so that the expansion of the steam performs useful work by driving a piston or otherwise producing mechanical energy. A boiler in this context, even if it uses thermal energy produced by certain of the systems and methods disclosed herein, is not acting as a thermal device, but is acting as part of an engine. By contrast, a boiler is operated to achieve a primary goal of heating a substance like water or steam is acting as a thermal device. A thermal device can produce heat by the same thermodynamic mechanism as an engine uses (for example, combustion), but the thermal device uses the thermal energy in an unmediated manner simply to produce heat: it lacks a prime mover to convert the thermal energy into useful work that can, in turn, produce mechanical or electrical energy.
The difference between a thermal device (i.e., a device used primarily for the production of heat) and a heat-driven engine is well demonstrated by cogeneration or combined-heat-and-power facilities, which can use the thermal energy produced by combustion not only to perform work such as driving a gas or steam-powered generator but also to heat water that can be used for process heating, building heating, and the like. The systems and methods for instantiating fuels and optionally oxidants as disclosed herein can be employed to produce thermal energy for both end-uses, the production of work and the unmediated production of heat. However, only those devices involved in the unmediated production of heat are thermal devices, although they can be combined with other systems using the production of heat to perform work.
Exemplary thermal devices and systems can include equipment for the production of thermal energy and the transfer of heat (termed “thermal equipment” herein) including, without limitation, furnaces, boilers, heaters, irons, warmers, ovens, stoves, dryers, annealers, kilns, bakers, cookers, sealers, smelters, solderers, torches, cutting torches, welders, melters, autoclaves, sterilizers, and the like and combinations thereof. Thermal equipment might be of any size, scale, scope, or use, including, without limitation, small, medium, large, personal, hobby, home, domestic, household, commercial, laboratory, hospital, factory, manufacturing, industrial, etc., and pieces of thermal equipment can be used separately or can be combined. As examples, a thermal system can be used as a home hot water heater or boiler heated by combustion of instantiated H2 and instantiated O2; an industrial furnace or boiler heated by the combustion of instantiated H2 as fuel and instantiated O2 as oxidant, or a welding/cutting device using instantiated gaseous acetylene as reactant (fuel) and ambient or instantiated gaseous O2 as oxidant.
In embodiments, a thermal device can include any flame, heater, or burner that performs the combustion of an instantiated reactant (such as a fuel or an oxidant) with another instantiated or non-instantiated reactant (such as, respectively, an oxidant or a fuel), with the production of heat that is transferred to a heat recipient to energize a chemical reaction therein. This operation of a thermal device for the initiation or propagation of chemical reactions in a heat recipient is seen, for example, in metal cutting operations (as opposed to metal welding), in which the heat from the metal cutting torch heats the metal to its kindling temperature, at which point the heat of the torch overcomes the activation energy for the metal's combustion, allowing it to become oxidized. Innumerable chemical reactions take place on the same principle: heat from a flame, burner, or the like raises the temperature of the heat recipient sufficiently to energize or to initiate a chemical reaction.
A thermal apparatus suitable for implementation in a thermal device and thermal system is capable of using any fuel that can be produced by a RA, or by a combination of multiple RAs. In other embodiments, the term “thermal apparatus” pertains to a RS in a thermal system that effects the reaction between the fuel reactant and an oxidant, wherein either the fuel or the oxidant or both is produced by a set of one or more RAs. In many thermal apparatus embodiments, hydrogen is the preferred fuel, although any material that can be produced by a RA (including without limitation lithium, sodium, potassium, ammonia, or hydrocarbons), or by a combination of various materials produced by RAs, is subject to consideration provided such fuel is compatible with (e.g., can be burned by) the apparatus. Any oxidizing agent that reacts appropriately with the fuel in the context of the apparatus can be employed (including without limitation: oxygen, fluorine, chlorine, bromine, hydrogen peroxide). While the oxidizing agent is advantageously oxygen in preferred embodiments, any chemical that reacts appropriately with the fuel and satisfies an implementation's constraints can be used as an oxidizing agent. The oxidizing agent can be instantiated (or filtered, or isolated, or extracted, or nucleated), collected, and managed by a system more or less similar to that assembling the fuel, but it is generally separated therefrom in order to prevent premature reaction between fuel and agent, until the fuel and agent are combined, combusted, or otherwise chemically reacted in the thermal apparatus with the agent being introduced into the thermal apparatus in the conventional way.
In preferred embodiments, the thermal apparatus will use hydrogen as the fuel and oxygen as the oxidant, and will produce the combustion of hydrogen in the presence of oxygen, i.e., sustain the ongoing exothermic chemical reaction as shown in EQ 1:
2H2 (g)+O2 (g)→2H2O (g) ΔH=−483.6 kJ EQ 1:
which produces a flame in the range of 3073K (2800° C., 5072° F.). An even hotter flame of 3773K (3500° C., 6,332° F.) can be attained in oxyacetylene embodiments wherein instantiated acetylene is burned in the presence of instantiated pure oxygen). In certain embodiments, the hydrogen fuel is instantiated or filtered, or isolated, or extracted, or nucleated by one or more RAs, and the oxygen is drawn from the atmosphere or from another oxygen source. In other embodiments, at least one auxiliary RA can be used to produce oxygen or the oxidizing agent of choice. Implementations can also use additional RAs configured to produce a supply of oxidizing agent to react with the fuel. Producing the oxidizing agent within the system can advantageously allow the thermal device to produce very hot flames, for example an oxyhydrogen flame for metal-cutting applications. In embodiments, the ability to produce the oxidizing agent within the system permits it to be used in environments where ambient oxygen is scarce or unavailable, such as underwater (e.g., submarines), or in confined or unvented places (e.g., vaults, tunnels, and mines).
In certain embodiments, it can be advantageous to moderate the heat produced by the system: for example, the very hot adiabatic flame temperature of the stoichiometric reaction of hydrogen and oxygen (2800° C.) may be too extreme and therefore undesirable for food preparation. The reaction temperature can be reduced by including other materials as secondary streams that do not participate in, or contribute much heat to, the exothermic reaction but that rather absorb heat and thereby lower the effective temperature produced by the primary reaction. Such moderating (“buffering”) materials might include for example, without limitation: excess fuel, excess oxidizer, or other gases such as nitrogen, helium, argon, krypton, etc. Effective temperature of the thermal apparatus can also be moderated, without limitation, by buffering a hot flame with stone, ceramic, brick, or other intermediating material which re-emits the heat in a milder, less intense form, or by other techniques familiar to those of ordinary skill in the art.
Reaction products can be directed out of the thermal apparatus 1004 as exhaust 1028. The thermal energy 1030 produced by the thermal apparatus 1004 can be directed to any appropriate heat recipient 1032 and transferred thereto using any form of heat transfer, including radiation, conduction, convection, or a combination thereof. As would be understood by skilled artisans, the particular configuration of the intake ports 1020, 1022, the reaction/combustion chamber or other structure, and the manner of emitting or otherwise using and handling the resulting thermal energy 1030 together with the byproduct exhaust 1028, if any, will depend on the particular type of thermal apparatus 1004. The chemical reaction between the fuel instantiated or filtered, or isolated, or extracted, or nucleated, by the set of RAs 1002 and the oxidant provided by the air/oxygen/oxidant intake 1012 as performed by the thermal apparatus 1004 is the source of the thermal energy 1030 that provides the heat transfer to the heat recipient 1032. A computer system 1040 receives data from the components of the system and controls their activity and interaction, including without limitation the sensing, direction, and regulation of heat transfer 1030 from the thermal apparatus 1004 to the heat recipient 1032. Illustrative pathways for receiving/transmitting data are shown schematically as dotted lines W, X, Y, and Z in the Figure, although it is understood that other appropriate pathways for sensing, directing, and regulating aspects and components of the system can exist in addition to those depicted by the dotted lines.
In certain embodiments, hydrogen is a preferred fuel to be produced by the RAs 2500 (1-N), although it is understood that any material that can be produced by a RA either in isolation or in combination with other materials that can be produced by another RA can be used as a fuel to be introduced into the thermal apparatus 2700. Ultimately, the fuel instantiated by the RAs 2500 (1-N) is delivered to fuel intake port 2750 of the thermal apparatus 2700, where it is used in a reaction with the oxidizing agent from the RAs 2550 (1-M) introduced through the oxidizing agent intake port 2780, to produce heat in a conventional and well-understood manner. Any oxidizing agent that reacts appropriately with the fuel can be considered, including but not limited to oxygen. In embodiments, the thermal system 2301 can draw some or all oxygen from the atmosphere or from other oxygen sources such as tanks or gas lines, in which case the RAs 2550 that produce oxygen, as shown in this Figure, are replaced by conduits to permit the ingress of oxygen from these other sources, allowing the oxygen to enter the thermal apparatus 2700 for example through a conduit 2600′ and the intake port 2780, replacing the oxygen that is produced by RAs such as are shown in the depicted embodiment. As shown in this Figure, the thermal system 2301 uses a conduit 2600/2600′ to convey fuel/oxidant to the appropriate intake port 2750/2780 of the thermal apparatus 2700. In embodiments, at least one auxiliary RA 2550 can be used to produce some or all of the oxygen needed. In yet other embodiments, not shown in this Figure, certain RAs from the fuel-producing bank or set of RAs 2500 or from the oxidizing agent bank or set of RAs 2550 can be designated to produce a moderating material (such as, without limitation, helium, nitrogen, argon, water vapor, etc.) that can be mixed with, and/or introduced with, the fuel (and/or oxidizing agent) to lower the effective combustion temperature. It is also possible for there to be additional RAs (not shown) and conduits (also not shown) to separately produce and deliver a moderating material to thermal apparatus 2700 to dilute and cool the reaction heat. In embodiments, the system can include a temperature regulating subsystem (not shown), which can be automatic, semi-automatic, and/or manual, that can affect the temperature by methods including controlling the production, flow and/or delivery of at least one of the fuel, oxidizing agent, or moderating material.
As the fuel/oxidant is assembled and emitted by the at least RAs 2500/2550, it can be collected and introduced into the thermal apparatus 2700 directly, (e.g., at the fuel/oxidant intake port 2750/2780). However, it is understood that the fuel and oxidant can also each undergo additional processing steps (not shown) during their passage to the thermal apparatus 2700. Such processing steps can include, without limitation, being: pumped, collected, combined, e.g., combined with the output of other conduits or sources, pressurized, compressed, liquefied, solidified, stored, packaged, transported, hauled, unpackaged, repackaged, gasified, uncompressed, depressurized, filtered, mixed, agitated, centrifuged, shaken, oscillated, stirred, vibrated, gated, shunted, injected, diverted, merged, blown, aerated, propelled, spun, blended, dissolved, extracted, sensed, tested, humidified, dehumidified, monitored, measured, regulated, accumulated, cooled, heated, or otherwise processed. Such operations may involve the use of components including for example and without limitation: pumps, sensors, gates, shunts, injectors, valves, baffles, pipes, splitters, plumbing, relays, filters, controls, accumulators, tanks, containers, reservoirs, fans, blowers, propellers, impellors, aerators, agitators, oscillators, vibrators, shakers, stirrers, centrifuges, pressurizers, humidifiers, dehumidifiers, compressors, refrigerators, blenders, mixers, vats, dissolvers, extractors, coolers, heaters, gasifiers, liquefiers, and sensors and controls for flow, humidity, concentration, density, purity, particle size, particle diameter, particle surface area, particle weight, viscosity, temperature, volume, and pressure, as well as other sensors and controls and processing equipment. In situations where additional processing steps are carried out, each step may be performed zero or more times, and the order in which they are performed (and whether they are necessary) depends on the requirements of the particular thermal system 2301.
In the depicted embodiment, the RAs 2500/2550 receive power as needed, from battery 2200 or other electrical storage cell (e.g., a capacitor) or electrical power source (such power may be governed by a start switch in some implementations). Aspects of the operation of each RA 2500/2550 are sensed, monitored, coordinated, regulated and controlled by a processor 2100 through sensor/control line(s) 2300/2300′. Regulation can include parameters such as, without limitation, power, temperature, humidity, configuration, pressure, flow, concentration, viscosity, density, purity, particle dimension, and any other relevant state or parameter; together with the operation of fans, blowers, oscillators, pumps, valves, reservoirs, accumulators, pressurizers, compressors and/or other devices used to support the processes shown.
As depicted in 12, a computer processor 2100 senses, monitors, coordinates, regulates, and controls the various other aspects of the thermal system 2301, and is connected as needed to the other various components to receive sensor input signals and send control signals. Processor 2100 receives operating power 2120 from the battery 2200, from which it may also receive sensory signals 2140 and to which it may send control signals 2160. In embodiments, the thermal system 2301 can have connections beyond those specifically illustrated here, from processor 2100 to other components; in other embodiments, certain connections illustrated in
An operator activates the thermal system 2301 by turning the On-Off Switch to “on”. This gates power from battery 2200 to the other components as appropriate, including processor 2100, and the banks or sets of RAs 2500, 2550. The banks or sets of RAs 2500, 2550 are started under command and control of processor 2100 as the appropriate environment is established, including for example and without limitation: temperature, humidity, pressure, charge, electromagnetic fields. This involves sensors and controls in the banks or sets of RAs 2500, 2550, the signals of which are transmitted through sensor/control lines 2300/2300′ to and from the processor 2100. Power as appropriate is delivered to the RAs in the banks or sets of RAs 2500, 2550 through power conductors 2400/2400′. Once the RAs 2500, 2550 and their environment are suitably prepared, the banks or sets of RAs 2500, 2550 are operationally activated under command and control of processor 2100, which thereafter senses, monitors, coordinates, regulates, and controls the banks or sets of RAs 2500, 2550 to ensure proper operation.
In their active state, RAs 2500 instantiate, or filter, or isolate, or extract, or nucleate, the fuel, which in an exemplary embodiment comprises hydrogen atoms and molecules. The instantiated fuel emitted by the fuel-producing RAs 2500 is collected by the conduit 2600, and is further processed by optional processing steps (denoted by 2670) as appropriate before the fuel is delivered to the thermal apparatus 2700 through its fuel intake 2750. If necessary, 2670 can represent various additional steps and/or structures, as described above.
For embodiments in which the oxidizing agent is oxygen drawn from the atmosphere, it is extracted and processed in a conventional fashion and introduced into the thermal apparatus 2700 at its oxidizing agent intake port 2780. In some embodiments, the oxidizing agent is assembled by the bank or set of RAs 2550, and delivered through conduit 2600′ to the oxidizing agent intake port 2780 of the thermal apparatus 2700, where it is used in the reaction with the fuel to produce heat and other radiant energy via conventional reactions. Conduit 2600′ may deliver the oxidizing agent for optional processing steps (denoted by 2670′) as appropriate before the oxidizing agent is introduced into the thermal apparatus 2700 through its oxidizing agent intake 2780. If necessary, 2670′ may involve various additional steps and/or structures, as described above.
As shown in
In more detail, exothermic reactions produced by reacting (a) a first reactant (e.g., a fuel instantiated, or filtered, or isolated, or extracted, or nucleated by the thermal apparatus according to the present invention or obtained elsewhere provided that the reaction involves a second reactant is instantiated, or filtered, or isolated, or extracted, or nucleated by a RA system as disclosed herein) with (b) a second reactant (e.g., an oxidizing agent that can be instantiated, or filtered, or isolated, or extracted, or nucleated by a RA system as disclosed herein, or obtained elsewhere provided that the first reactant is instantiated, or filtered, or isolated, or extracted, or nucleated by a RA system as disclosed herein) yield thermal energy that can be transferred as heat to a body or an environment external to the source of the thermal energy. Such transfers result in a change in temperature from the source of the thermal energy to the external recipient via heat transfer. As an example, the exothermic reaction mentioned in EQ1 above combines hydrogen fuel and oxygen to produce water, yielding 241 kJ/mole of heat that can be transferred to other bodies or environments. By producing a fuel that can support an exothermic chemical reaction, the systems and methods disclosed herein can energize a thermal apparatus for the production of thermal energy. Transferring this thermal energy from the source (the thermal apparatus) to the external body or environment entails heat transfer.
As mentioned previously, heat transfer takes place by conduction, convection, radiation, or some combination thereof. In thermal conduction, the thermal energy is transferred as heat due to the migration of free electrons or the excitation of lattice vibrational waves (phonons) between the higher-temperature heat source and the lower-temperature heat recipient. Conduction most commonly involves the contact of one object or fluid with another, but without any significant movement of mass in the direction of the energy flow, such as takes place when a solid body comes into contact with another solid body, with a transfer of thermal energy from one to another. Conduction is involved in everyday activities such as cooking food in a skillet or pressing clothes with an iron. By contrast, thermal convection transfers thermal energy as heat due to the bulk movement of molecules within fluids, whether liquid or gas. Convection takes place, for example, when water is heated in a pan or when clothes are dried in a dryer. Conduction and convection involve objects or materials as both heat source and heat recipient, but convection involves the presence of fluid motion as the heat is transferred from heat source to heat recipient, while conduction does not. Thermal energy can also be transferred by emanation from a heat source without involving any transfer medium, with the heat being transferred in the form of electromagnetic radiation particularly in the infrared region of the electromagnetic spectrum. This type of heat transfer, termed thermal radiation, conveys heat from a heat donor to a non-contiguous heat recipient without involving a fluid transfer medium. Thermal energy travels by radiation when the sun warms the Earth's surface or when an open flame warms the space around it.
As previously described, the thermal systems according to the principles of the invention comprise a thermal apparatus and further comprise those mechanisms or subsystems for the transfer of the thermal energy from the thermal apparatus to the heat recipient, i.e., heat transfer. Thermal systems as disclosed herein can transfer heat by any of the known forms of heat transfer processes, whether conduction, convection, radiation, or some combination thereof. Conduction as performed by a thermal system is a heat transfer process that occurs within a heat recipient due to the energy of the molecules, atoms, or other component of that substance, related to its intrinsic properties, without macroscopic movement of any of its parts. Convection as performed by a thermal system is a combined type of heat transfer occurring in a heat recipient fluid that includes both heat conduction within the fluid and macroscopic motion in the fluid. The thermal energy produced by the thermal apparatus excites the molecules in the heat recipient fluid, producing motion therein due to diffusive and bulk current flows, including motion due to thermal expansion, density/buoyancy forces, and phase changes. Thermal radiation as performed by a thermal system is energy transfer in the form of electromagnetic waves. Energy transport takes place by photons released by molecules and atoms involved in the reaction that produces the thermal energy, with that energy being conveyed in electromagnetic waves: the wavelengths of electromagnetic waves generated by heated bodies are in the range of 0.3-10 μm. Radiation with a longer wavelength than the visible spectrum of electromagnetic radiation is termed infrared, and radiation with a shorter wavelength than the visible spectrum is termed ultraviolet. Thermal radiation, because it involves no intervening medium between heat source and heat recipient, can transfer heat in a vacuum. Thermal systems in accordance with the principles of the invention can use any of the aforesaid mechanisms alone or in combination to produce the desired transfer of heat produced by the thermal apparatus to the heat recipient. In embodiments, the combustion in the thermal apparatus transfers the thermal energy by radiation and does not involve any intermediation between heat source and heat recipient. In other embodiments, the thermal apparatus transfers the thermal energy (i.e., produces heat) in the heat recipient by conduction or convection. In yet other embodiments, there is some combination of the various forms of heat transfer in the thermal device.
In exemplary embodiments, a thermal system in accordance with the principles of the invention can be used for residential or industrial furnaces, which can include hot water heaters, boilers, and the like. In such as system, whether a furnace or a hot water heater or boiler, combustion provides a source of thermal energy, which is then transferred to a heat recipient, for example a metal being heated directly by a furnace, or a fluid that is employed to transfer the heat to a secondary recipient or environment. In a conventional industrial furnace, hot water heater or boiler, combustion takes place in a burner or firebox, which often involves burning fossil fuels (e.g., coal, coke, oil, wood, etc.) in the presence of atmospheric oxygen to produce thermal energy. The thermal energy so produced is then transferred to a closed set of fluid-containing tubes or coils residing in the firebox. This section of the furnace is termed the “radiant section” of the furnace because the thermal energy produced by the combustion in that area is transmitted by radiation into the tubes containing the fluid. The fluid-containing tubes are arranged so that they extend into an adjacent “convection” section of the furnace that is separate from and walled off from the radiant section. In the convection section, the heated fluid within the tubes transfers heat by convection to other, secondary, fluids that surround them. These secondary fluids, for example heat transfer liquids, can then transfer heat to other locations in the form of heated liquids or heated gases (such as is seen, for example, in a boiler, which produces steam from heating water). Alternatively, the heat carried by the tubes into the convection section can be used to heat the local environment within the convection section without involving secondary fluids for heat transfer. In this case, the heated tubes transfer heat to the ambient gases in the convection section, providing an oven-like atmosphere within the convection section in which a product or a material can be heated directly.
Thermal systems in accordance with the principles of the invention can be used in furnaces, heaters, boilers, and the like to instantiate, or filter, or isolate, or extract, or nucleate, the reactants for combustion and to effect their combustion, thereby precluding or supplementing the need for conventional, hydrocarbon-based fuels and/or conventionally derived oxidizing agents in such devices. In embodiments, a combination of a fuel (such as hydrogen) produced by a set of one or more RAs and an oxidant (such as oxygen) produced by a second set of one or more RAs can be combusted in the radiant section of the furnace, heater, or boiler to produce the thermal energy for the system's overall function. In other embodiments, only one of a fuel and an oxidant is produced by the set of one or more RAs, while the other reactant is provided by conventional sources. In either case, the systems and methods disclosed herein offer convenient and scalable alternatives to the fossil-fuel-derived sources of thermal energy used for conventional industrial and residential furnaces, heaters, and boilers. Advantageously, hydrogen thus produced can be used as a fuel source and oxygen can be used as the oxidant, thereby avoiding the CO2 associated with conventional hydrocarbon-powered furnaces, heaters, and boilers; in this embodiment, one or both of the reactants can be produced using a set of one or more RAs as disclosed herein. In a particularly advantageous embodiment, both the fuel and the oxidant for the combustion process (here hydrogen and oxygen) are produced by sets of one or more RAs.
In another exemplary embodiment, a thermal system can be used for metalworking such as welding, for example as a substitute for conventional oxyfuel welding. Oxy-fuel welding is a process that uses the combustion of a fuel gas and oxygen to generate a flame in a delivery device (a “torch”) having sufficient heat to melt metal so that two metal surfaces can be joined. The flame temperature produced by the welding system is sufficient to allow localized melting of the workpieces to which it is applied. The torch applies the flame to the workpieces, creating localized areas of molten metal on each; as the areas of localized melting merge and resolidify, the two metal workpieces become bonded to each other. Hydrocarbon-oxygen flames and hydrogen-oxygen flames can be used for welding, with the former having a range of temperatures depending on the fuel substance used (e.g., acetylene at 3500° C.), and with the latter producing an adiabatic temperature of about 2800° C. Heat produced by the combustion of the reactants within the welding torch is transmitted to the workpieces (the heat recipients) by radiation at a sufficient temperature to ultimately melt the targeted portions thereof. Heat from the flame reaching the surface of each heat recipient (each, a workpiece) is then conducted throughout the targeted portion of the metals being welded, heating those areas of the metals sufficiently to change their states from solid to liquid, thereby creating a localized pool of melted metal. An additional metal, called a “filler,” is generally provided, which also melts into the localized pool and solidifies with the target metal(s), offering enhancements to the solidification process and the resulting bond between the workpieces. Equipment for conventional welding comprises a fuel source and an oxidant source (generally contained in cylinder tanks), each of which deliver the specific reactant under pressure through a conduit (a hose) to the torch, which applies the flame to the workpieces.
A thermal device according to the principles of the invention can provide instantiated fuel and/or oxidant that can be combusted to produce the flame for a welding torch. In more detail, in a thermal system according to the principles of the invention, the fuel and/or oxidant instantiated by their respective sets of one or more RAs can be directed through appropriate conduits into the welding torch for ignition and combustion, with the flame being directed towards the workpieces to perform the welding operation in accordance with practices familiar in the art. In an embodiment of a thermal system for welding, either the fuel source or the oxidant source or both is provided by the appropriate sets of one or more RAs, while the combustion process and further use of the thermal energy is performed in accordance with conventional welding practices.
While hydrogen is a preferred fuel for many applications, and oxygen a preferred oxidizing agent, the selection of the fuel is based on the needs of the welding procedure, as certain metals require higher temperatures for welding than others, and certain metals respond adversely to certain fuels used in the combustion process. For example, hydrogen is not used for welding ferrous materials because the introduction of non-combusted hydrogen (i.e., the presence of hydrogen atoms or ions) into the ferrous material causes a form of embrittlement known as hydrogen-induced cracking. Also, the combustion of hydrogen, producing a flame temperature of about 2800° C., may not produce enough thermal energy for welding certain metals, in contrast to the combustion of acetylene and oxygen, which produces a flame temperature between about 3200° C. and 3500° C., making this latter fuel more suitable for welding certain metals with higher melting points. In embodiments, fuel sources (whether provided conventionally or produced by a set of one or more RAs as disclosed herein) can be selected by the ordinarily skilled artisan to meet the needs of the particular welding operation, with the oxidant being generated by a set of one or more RAs as disclosed herein. In embodiments, a combination of a fuel (such as hydrogen) produced by a set of one or more RAs and an oxidant (such as oxygen) produced by a second set of one or more RAs can offer an advantageous alternative to conventional welding technologies. For example, a thermal system using the principles of the invention disclosed herein can be used in a thermal device suitable for underwater use; such a thermal device can provide a useful substitute for conventional oxyacetylene welding for use in submerged environments, because acetylene is unstable when stored in pressurized bottles/tanks; and explosive at pressures such as are found more than 10 meters underwater.
One hundred milligrams (100 mg) of powdered carbon was placed in a GG-EL graphite tubular reactor (15.875 mm) OD, with ID machined to ˜9 mm). This reactor was inserted into a reactor assembly
Referring to
Amperage harmonic patterning was then initiated on the reactor. With each amperage pattern (oscillation), the gases fed to the reactor can treated by the same or different light sequence. In one embodiment of the experimental protocol, the amperage of the reactor was increased to 78.5 amps over 1 second, the high-end harmonic pattern point. The amperage of the reactor was then decreased to 38.5 amps over 9 seconds and held at 38.5 amps for 3 seconds. Immediately at the start of the 3 second hold, an argon light 122 in position 1 (122; horizontal lamp orientation; at 180°; bulb tip pointing towards entrance plate at the optical entrance; 5.04 cm from the outer diameter of the gas line) was turned on. After the 3 second hold, amperage to the reactor was then ramped up to 78.5 amps over 9 seconds with a 3 second hold upon reaching 78.5 amps before a downward ramp was initiated. The reactor amperage was decreased to 38.5 amps, over 9 seconds and then held for 3 seconds. Immediately at the start of the 3 second hold, light 103 (103), a neon light in position 1, was turned on. The reactor amperage was again ramped up to 78.5 amps over 9 seconds, held there for 3 seconds, and then again ramped down to 38.5 amps over 9 seconds. A long-wave ultraviolet lamp (104; horizontal lamp orientation; at 90°; bulb tip facing entrance plate at the optical entrance; 5.04 cm from the outer diameter of the gas line) in position 1 was turned on.
The reactor was again ramped up to 78.5 amps over 9 seconds, held for 3 seconds, then decreased to 38.5 amps over another 9 seconds. Next a short-wave ultraviolet lamp (105 horizontal lamp orientation; 7.62 cm from inlet or entrance flange; at 270°; bulb tip at the optical entrance and facing the entrance plate; 5.04 cm from the outer diameter of the gas line) in the E/MEE (position 1) E/MEE section light was turned on and held for 3 seconds. The reactor was again ramped up to 78.5 amps over 9 seconds and held for 3 seconds. After the 3 second hold, the reactor amperage was decreased to 38.5 amps over another 9 seconds. The reactor was then held at 38.5 amps for 3 seconds, before another ramp up to 78.5 amps over 9 seconds was initiated. At 3 seconds into this ramp, lamp 107, in position 1 (107) was turned on and held there for the remaining 6 seconds of the 9 second total ramp. The reactor was held for 3 seconds in this condition.
The lights were turned off simultaneously in the E/MEE section as follows: (103), (108), (106), (105) and (104) and the reactor was deenergized. The reactor was held at this state, with continuous gas flow for 27 seconds during which the TEDLAR® bags are closed and removed. All remaining lights were turned off and gas flow continues for 240 seconds.
One hundred milligrams (100 mg) of powdered carbon was placed in a graphite tubular reactor (15.875 mm) OD, with ID machined to ˜9 mm), as described above and loaded into a closed end system. After ten closed end set-ups have been completed, each individual unit was loaded into the degassing oven openings and all incoming and outgoing lines were connected to the closed end systems. Isolated each incoming line to each reactor while maintaining the outgoing lines in an open position. Started the vacuum system until the vacuum gauge reads at least 750 mmHg. Upon reaching 750 MmHg, closed all outgoing line valves from the closed end systems and secured the vacuum pump. Performed a 30-minute leak test of the system. After successfully passing the leak check, opened each incoming line to the closed end system one at a time at 0.4 slpm N2. Once all incoming lines were open and the vacuum gauge reached a slight positive pressure, opened the outgoing gas line on the degassing oven. Started the degassing oven profile ramping from Tamb to 400° C. over 1 hour while maintaining N2 flow. After the 1-hour ramp, maintained flow for an additional hour for temperature stabilization while maintaining gas flow. After the temperature stabilization was complete, secured all incoming gas flows and isolated the degassing oven vent line. Immediately started the vacuum pump and begin the degassing protocol. Maintained the temperature and vacuum for 12 hours. After the 12 hours, allowed the oven to cool prior to closed end unit removal.

For the chemical analysis of gas samples in TEDLAR® bags, a test protocol was developed based on the standard test method established for internal gas analysis of hermetically sealed devices. Prior to sample measurement, system background was determined by following exact measurement protocol that is used for sample gas. For system background and sample, a fixed volume of gas was introduced to the Pfeiffer QMA 200M quadrupole mass spectrometer (QMS) system through a capillary. Through a capillary, a fixed volume of gas was introduced to the Pfeiffer QMA 200M quadrupole mass spectrometer (QMS) system. After sample gas introduction, the ion current for specific masses (same as masses analyzed for system background) were measured. During background and sample gas analyses total pressure of the QMS system was also recorded, allowing for correction of the measured ion current.
Measurements of the ion current for each mass were corrected to the average of measured background contributions corrected for pressure difference. Subsequent to the background correction, individual corrected mass signals were averaged and corrected to a known gas standard to determine the percent volume of 17 gas species. All corrections were determined using nitrogen and nitrogen-hydrogen mixture reference gases analyzed to match selected process gas for test samples using the developed protocol based on the standard test method, in accordance with Military Standard (MIL-STD-883) Test Method 1018, Microcircuits, Revision L, FSC/Area: 5962 (DLA, 16 Sep. 2019). Results below: 1%=10,000 ppm, Volume values for gas blanks and samples were produced using the developed gas analysis test method and validated using a gas mixture standard of 99.98% nitrogen and 0.02% hydrogen. All analytical performed by EAG Laboratories, Liverpool, NY using standard TEDLAR® bag gas sampling protocols and specified mass spectrometry methods.
