Description
TECHNICAL FIELD

The present technology relates generally to chemical reactors with annularly positioned reactant delivery devices and product removal devices, and associated systems and methods. In particular embodiments, reactor systems with these devices can be used to produce clean-burning, hydrogen-based fuels from a wide variety of feedstocks with enhanced energy efficiency, and can produce structural building blocks from carbon and/or other elements that are released when forming the hydrogen-based fuels.


BACKGROUND

Renewable energy sources such as solar, wind, wave, falling water, and biomass-based sources have tremendous potential as significant energy sources, but currently suffer from a variety of problems that prohibit widespread adoption. For example, using renewable energy sources in the production of electricity is dependent on the availability of the sources, which can be intermittent. Solar energy is limited by the sun's availability (i.e., daytime only), wind energy is limited by the variability of wind, falling water energy is limited by droughts, and biomass energy is limited by seasonal variances, among other things. As a result of these and other factors, much of the energy from renewable sources, captured or not captured, tends to be wasted.


The foregoing inefficiencies associated with capturing and saving energy limit the growth of renewable energy sources into viable energy providers for many regions of the world, because they often lead to high costs of producing energy. Thus, the world continues to rely on oil and other fossil fuels as major energy sources because, at least in part, government subsidies and other programs supporting technology developments associated with fossil fuels make it deceptively convenient and seemingly inexpensive to use such fuels. At the same time, the replacement cost for the expended resources, and the costs of environment degradation, health impacts, and other by-products of fossil fuel use are not included in the purchase price of the energy resulting from these fuels.


In light of the foregoing and other drawbacks currently associated with sustainably producing renewable resources, there remains a need for improving the efficiencies and commercial viabilities of producing products and fuels with such resources.

Representative Reactors and Associated Methodologies


FIG. 1 is a partially schematic illustration of a system 100 including a reactor vessel 110 having a reaction zone 111. The system 100 further includes a solar collector 101 that directs solar energy 103 to the reaction zone 111. The solar collector 103 can include a dish, trough, heliostat arrangement, fresnel lens and/or other radiation-focusing element. The reactor vessel 110 and the solar collector 101 can be mounted to a pedestal 102 that allows the solar collector 101 to rotate about at least two orthogonal axes in order to continue efficiently focusing the solar energy 103 as the earth rotates. The system 100 can further include multiple reactant/product vessels 170, including first and second reactant vessels 170a, 170b, and first and second product vessels, 170c, 170d. In particular embodiments, the first reactant vessel 170a can provide a reactant that contains hydrogen and carbon, such as methane, which is processed at the reaction zone 111 in an endothermic reaction to produce hydrogen and carbon which is provided to the first and second product vessels 170c, 170d, respectively. In other embodiments, other reactants, for example, municipal solid waste streams, biomass reactants, and/or other waste streams can be provided at a hopper 171 forming a portion of the second reactant vessel 170b. In any of these embodiments, an internal reactant delivery system and product removal system provide the reactants to the reaction zone 111 and remove the products from the reaction zone 111, as will be described in further detail later with reference to FIGS. 3-6.


The system 100 can further include a supplemental heat source 180 that provides heat to the reaction zone 111 when the available solar energy 103 is insufficient to sustain the endothermic reaction at the reaction zone 111. In a particular embodiment, the supplemental heat source 180 can include an inductive heater 181 that is positioned away from the reaction zone 111 during the day to allow the concentrated solar energy 103 to enter the reaction zone 111, and can slide over the reaction zone 111 at night to provide heat to the reaction zone 111. The inductive heater 181 can be powered by a renewable clean energy source, for example, hydrogen produced by the reactor vessel 110 during the day, or falling water, geothermal energy, wind energy, or other suitable sources.


In any of the foregoing embodiments, the system 100 can further include a controller 190 that receives input signals 191 and directs the operation of the devices making up the system 100 via control signals or other outputs 192. For example, the controller 190 can receive a signal from a radiation sensor 193 indicating when the incident solar radiation is insufficient to sustain the reaction at the reaction zone 111. In response, the controller 190 can issue a command to activate the supplemental heat source 180. The controller 190 can also direct the reactant delivery and product removal systems, described further below with reference to FIGS. 3-6.



FIG. 2 is a partially schematic illustration of an embodiment of the reactor vessel 110 shown in FIG. 1, illustrating a transmissive component 112 positioned to allow the incident solar energy 103 to enter the reaction zone 111. In a particular embodiment, the transmissive component 112 can include a glass or other suitably transparent, high temperature material that is easily transmissible to solar radiation, and configured to withstand the high temperatures in the reaction zone 111. For example, temperatures at the reaction zone 111 are in some embodiments expected to reach 4000° F., and can be higher for the reactants and/or products.


In other embodiments, the transmissive component 112 can include one or more elements that absorb radiation at one wavelength and re-radiate it at another. For example, the transmissive component 112 can include a first surface 113a that receives incident solar energy at one wavelength and a second surface 113b that re-radiates the energy at another wavelength into the reaction zone 111. In this manner, the energy provided to the reaction zone 111 can be specifically tailored to match or approximate the absorption characteristics of the reactants and/or products placed within the reaction zone 111, Further details of representative re-radiation devices are described in co-pending U.S. Application No. ______ titled, “CHEMICAL REACTORS WITH RE-RADIATING SURFACES AND ASSOCIATED SYSTEMS AND METHODS” (Attorney Docket No, 69545.8603US) filed concurrently herewith and incorporated herein by reference.


In other embodiments, the reactor vessel 110 can include other structures that perform related functions, For example, the reactor vessel 110 can include a Venetian blind arrangement 114 having first and second surfaces 113a, 113b that can be pivoted to present one surface or the other depending upon external conditions, e.g., the level of incident solar energy 103, hi a particular aspect of this embodiment, the first surface 113a can have a relatively high absorptivity and a relatively low emissivity, This surface can accordingly readily absorb radiation during the day. The second surface 113b can have a relatively low absorptivity and a relatively high emissivity and can accordingly operate to cool the reaction zone 111 (or another component of the reactor 110), e.g., at night. A representative application of this arrangement is a reactor that conducts both endothermic and exothermic reactions, as is described further in co-pending U.S. Application No. ______ titled “REACTOR VESSELS WITH PRESSURE AND HEAT TRANSFER FEATURES FOR PRODUCING HYDROGEN-BASED FUELS AND STRUCTURAL ELEMENTS, AND ASSOCIATED SYSTEMS AND METHODS” (Attorney Docket No. 69545.8616U8). Further details of other arrangements for operating the solar collector 101 (FIG. 1) in a cooling mode are described in co-pending U.S. Application No. ______ titled “REACTORS FOR CONDUCTING THERMOCHEMICAL PROCESSES WITH SOLAR HEAT INPUT, AND ASSOCIATED SYSTEMS AND METHODS” (Attorney Docket No. 69545.8606US), filed concurrently herewith and incorporated herein by reference.


In still further embodiments, the reactor 110 can include features that redirect radiation that “spills” (e.g., is not precisely focused on the transmissive component 112) due to collector surface aberrations, environmental defects, non-parallel radiation, wind and/or other disturbances or distortions. These features can include additional Venetian blinds 114a that can be positioned and/or adjusted to redirect radiation (with or without wavelength shifting) into the reaction zone 111.



FIG. 3 is a partially schematic, cross-sectional illustration of a portion of a reactor vessel 110 configured in accordance with an embodiment of the present disclosure. In one aspect of this embodiment, the reactor 110 includes a reactant delivery system 130 that is positioned within a generally cylindrical, barrel-shaped reactor vessel 110, and a product removal system 140 positioned annularly inwardly from the reactant delivery system 130. For example, the reactant delivery system 130 can include an outer screw 131, which in turn includes an outer screw shaft 132 and outwardly extending outer screw threads 133. The outer screw 131 has an axially extending first axial opening 135 in which the product removal system 140 is positioned. The outer screw 131 rotates about a central rotation axis 115, as indicated by arrow O. As it does so, it carries at least one reactant 134 (e.g., a gaseous, liquid, and/or solid reactant) upwardly and to the right as shown in FIG. 3, toward the reaction zone 111. As the reactant 134 is carried within the outer screw threads 133, it is also compacted, potentially releasing gases and/or liquids, which can escape through louvers and/or other openings 118 located annularly outwardly from the outer screw 131. As the reactant 134 becomes compacted in the outer screw threads 133, it forms a seal against an inner wall 119 of the vessel 110. This arrangement can prevent losing the reactant 134, and can instead force the reactant 134 to move toward the reaction zone 111. The reactant delivery system 130 can include other features, in addition to the outer screw threads 133, to force the reactant 134 toward the reaction zone 111. For example, the inner wall 119 of the reactor vessel 110 can include one or more spiral rifle grooves 116 that tend to force the reactant 134 axially as the outer screw 131 rotates. In addition to, or in lieu of this feature, the entire outer screw 131 can reciprocate back and forth, as indicated by arrow R to prevent the reactant 134 from sticking to the inner wall 119, and/or to release reactant 134 that may stick to the inner wall 119. A barrel heater 117 placed near the inner wall 119 can also reduce reactant sticking, in addition to or in lieu of the foregoing features. In a least some embodiments, it is expected that the reactant 134 will be less likely to stick when warn


The reactant 134 can include a variety of suitable compositions, e.g., compositions that provide a hydrogen donor to the reaction zone 111. In representative embodiments, the reactant 134 can include biomass constituents, e.g., municipal solid waste, commercial waste, forest product waste or slash, cellulose, lignocellulose, hydrocarbon waste (e.g., tires), and/or others. After being compacted, these waste products can be highly subdivided, meaning that they can readily absorb incident radiation due to rough surface features and/or surface features that re-reflect and ultimately absorb incident radiation. This property can further improve the efficiency with which the reactant 134 heats up in the reaction zone 111.


Once the reactant 134 has been delivered to the reaction zone 111, it receives heat from the incident solar energy 103 or another source, and undergoes an endothermic reaction. The reaction zone 111 can have an annular shape and can include insulation 120 to prevent heat from escaping from the vessel 110. In one embodiment, the endothermic reaction taking place at the reaction zone 111 includes dissociating methane, and reforming the carbon and hydrogen constituents into elemental carbon and diatomic hydrogen, or other carbon compounds (e.g., oxygenated carbon in the form of carbon monoxide or carbon dioxide) and hydrogen compounds. The resulting product 146 can include gaseous portions (indicated by arrow G), which passed annularly inwardly from the reaction zone 111 to be collected by the product removal system 140, Solid portions 144 (e.g., ash and/or other byproducts) of the product 146 are also collected by the product removal system 140.


The product removal system 140 can include an inner screw 141 positioned in the first axial opening 135 within the outer screw 131. The inner screw 141 can include an inner screw shaft 142 and inner screw threads 143. The inner screw 141 can also rotate about the rotation axis 115, as indicated by arrow I, in the same direction as the outer screw 131 or in the opposite direction. The inner screw 141 includes a second axial passage 145 having openings that allow the gaseous product G to enter. The gaseous product G travels down the second axial opening 145 to be collected and, in at least some instances, further processed (e.g., to isolate the carbon produced in the reaction from the hydrogen produced in the reaction). In particular embodiments, the gaseous product C can exchange additional heat with the incoming reactant 134 via an additional heat exchanger (not shown in FIG. 3) to cool the product C and heat the reactant 134. hi other embodiments, the gaseous product C can be cooled by driving a Stirling engine or other device to generate mechanical and/or electric power. As the inner screw 141 rotates, it carries the solid portions 144 of the product 146 downwardly and to the left as shown in FIG. 3. The sold products 144 (and the gaseous product C) can convey heat via conduction to the outer screw 130 to heat the incoming reactant 134, after which the sold portions 144 can be removed for use. For example, nitrogenous and/or sulfurous products from the reaction performed at the reaction zone 111 can be used in agricultural or industrial processes. The products and therefore the chemical and physical composition of the sold portions can depend on the characteristics of the incoming reactants, which can vary widely, e.g., from municipal sold waste to industrial waste to biomass.


As discussed above with reference to FIGS. 1 and 2, the system 100 can include features that direct energy (e.g., heat) into the reaction zone 111 even when the available solar energy is insufficient to sustain the reaction, in an embodiment shown in FIG. 3, the supplemental heat source 180 can include combustion reactants 182 (e.g., an oxidizer and/or a hydrogen-containing combustible material) that is directed through a delivery tube 184 positioned in the second axial opening 145 to a combustor or combustor zone 183 that is in thermal communication with the reaction zone 111. During the night or other periods of time when the incident solar energy is low, the supplemental heat source 180 can provide additional heat to the reaction zone 111 to sustain the endothermic reaction taking place therein.


One feature of an embodiment described above with reference to FIG. 3 is that the incoming reactant 134 can be in close or intimate thermal communication with the solid product 144 leaving the reaction zone. In particular, the outer screw shaft 132 and outer screw threads 133 can be formed from a highly thermally conductive material, so as to receive heat from the solid product 144 carried by the inner screw 141, and deliver the heat to the incoming reactant 134. An advantage of this arrangement is that it is thermally efficient because it removes heat from products that would otherwise be cooled in a manner that wastes the heat, and at the same time heats the incoming reactants 134, thus reducing the amount of heat that must be produced by the solar concentrator 101 (FIG. 1) and/or the supplemental heat source 180. By improving the efficiency with which hydrogen and/or carbon or other building blocks are produced in the reactor vessel 110, the reactor system 100 can increase the commercial viability of the renewable reactants and energy sources used to produce the products.



FIG. 4 is a partially schematic, cross-sectional illustration of an embodiment of the reactor vessel 110 having an outer screw 431 particularly configured to compact the reactant 134 that it carries. In this embodiment, the outer screw 431 includes a screw shaft 432 that tapers outwardly, thus reducing the radial width W of the screw threads 433 in an axial direction toward the reaction zone 111. This arrangement effectively reduces the volume between neighboring screw threads 433 in a direction toward the reaction zone 111, thus compacting the reactant 134. Over at least one portion of its length, the outer screw 431 can effectively remove air and moisture from the reactant 134, allowing the air and moisture to be withdrawn through the openings/louvers 118. These constituents might otherwise slow the rate of reaction at the reaction zone 111. As the reactant 134 is further compacted, it also seals against the inner wall 119 of the reactor vessel 110 to prevent liquids and gases from escaping when they might otherwise participate in the reaction at the reaction zone 111. The heat produced when compacting the reactant 134 can reduce the amount of energy required to be produced by the solar concentrator 101 (FIG. 1) or other energy source.


In other embodiments, other mechanisms and devices can be used to compact the reactant 134 as it is directed to the reaction zone 111. For example, FIG. 5 illustrates a reactor vessel 110 having an outer screw 531 with a shaft 532 carrying screw threads 533 that have a closer or smaller axial spacing (indicated by gap S) the closer the threads 533 are to the reaction zone 111. Accordingly, the pitch of the screw threads 533 can gradually decrease in an axial direction along the rotation axis 115. In any of the foregoing embodiments, the volume between neighboring threads is smaller proximate to the reaction zone 111 than it is distal from the reaction zone 111.


In the embodiments described above with reference to FIGS. 3-5, the reactant 134 is delivered and compacted by a spiral screw. In other embodiments, the reactant 134 can be delivered and compacted via other mechanisms, for example, a piston. FIG. 6 is a partially schematic, cross-sectional illustration of the reactor vessel 110 in which the reactant 134 is loaded on or ahead of a ring-shaped piston 150 that moves back and forth as indicated by arrow R within the reactor vessel 110. After the loading operation, the piston 150 drives toward the reaction zone 111, thus compacting the reactant 134 against an inwardly tapering vessel inner wall 119, which forms a tapered channel 121.


In one mode of operation, the piston 150 drives the reactant 134 against the tapered vessel inner wall 119, and then is withdrawn to allow more reactant to be placed in the reactor vessel 110. The additional reactant 134 is then driven against the reactant 134 already present between the vessel inner walls 119, thus forcing the reactant 134 entirely through the tapered channel 121 and into the reaction zone 111. This process can be repeated to deliver the reactant 134 to the reaction zone 111 in a series of pulses or steps.


In another mode of operation, the piston 150 can be formed from a material that collapses or compresses in a radial direction R1, thus allowing the piston 150 to drive entirely through the tapered channel 121 to deliver the entire amount of reactant 134 within the tapered channel 121 in one stroke. In other embodiments, the reactor 110 can include other arrangements for compacting the incoming reactant 134, while allowing the hot, exiting product to preheat the reactant 134 and thus reduce the amount of thermal energy that must be provided at the reaction zone 111 via solar or other sources to sustain an endothermic reaction.


From the foregoing, it will be appreciated that specific embodiments of the technology have been described herein for purposes of illustration, but that various modifications may be made without deviating from the technology. For example, reactions at the reaction zone 111 can be conducted on reactants other then methane. Such reactants can include other hydrocarbons, or other hydrogen donors that do not include carbon. Such hydrogen donors can include nitrogenous donors, and/or donors that include boron, silicon, or sulfur. Nitrogenous donors can include biomass constituents and/or other constituents. The solar collector can have a dish shaped arrangement, as shown in FIG. 1, or other arrangements (e.g., a trough shape or a heliostat arrangement) in other embodiments. Embodiments of the supplemental heat source described above were described in the context of an inductive heater and a combustor. In other embodiments, the supplemental heat source can include other devices that provide energy to the reaction zone 111 Reactors in accordance with still further embodiments do not receive heat from solar energy and accordingly can rely on what (in some embodiments described above) is considered a supplemental heat source, as a primary heat source.


Certain aspects of the technology described in the context of particular embodiments may be combined or eliminated in other embodiments. For example, the outer screw can include both a tapered screw shaft and varying spacing between adjacent threads to compact the reactant 134. In particular embodiments, the outer screw carries the reactant and the inner screw carries the solid products. In other embodiments, the roles of the inner and outer screws can be reversed. The arrangement described above with reference to FIG. 6 identified a piston positioned annularly outwardly from an inner threaded shaft. In other embodiments, an additional piston can replace the inner threaded shaft, or an inner piston can be used in conjunction with an outer threaded shaft. Further, while advantages associated with certain embodiments of the technology have been described in the context of those embodiments, other embodiments may also exhibit such advantages, and not all embodiments need necessarily exhibit such advantages to fall within the scope of the present disclosure. Accordingly, the present disclosure and associated technology can encompass other embodiments not expressly shown or described herein.
