The present invention uses some concepts, such as the modification in the oxygen donation characteristic throughout the combustion reaction, in the combustion chamber in systems, such as automotive vehicles, generators, locomotives, boats and ships.
The present invention allows numerous modifications and adaptations to the proposed means, creating a family of natural products with different molecular weights, based on natural oxygen donor alcohols and their substitutes, all of vegetable origin, as well as their modifications. The present invention also makes use of mineral media and chemical structures of higher molecular weight, known as polyalcohol in the form of polyols.
The characteristics of the present invention will be described below, including the reaction steps, some examples, and details of the processes.
The present invention deals with potentializing the concepts of partial and complete combustion through hydrocarbons in specific internal combustion chambers, designed for conventional systems such as the Diesel cycle and the Otto cycle, specifying the thermodynamic conditions, considering the action of the principles included in the process described here.
The principles are enhancement of intermolecular forces by atomic organization, radiation and electrolysis or electro-oxidation of a colloidal nanometer dispersion.
That said, the increase in intermolecular forces by atomic organization can be defined as the ability of a given structure to increase its intermolecular forces through atomic self-organization. Intermolecular forces can be defined as the capacity for electronic action, between atoms, in the form of molecular attraction or repulsion. Intermolecular forces can be divided into dipole-dipole, Van der Waals forces and hydrogen bonds. Intermolecular forces define the electrical potential of molecules. The greater its intermolecular forces, the greater its electrical potential.
Given the nature of intermolecular forces and self-organization of molecules, a specific wave frequency range can interfere with electrons in such a way as to cause an increase in intermolecular forces between miscible molecules of polar solvents with nonpolar solvents.
Through the oxidation of a colloidal nanometric dispersion, with defined particle size and frequency, it is possible to transform an alcohol molecule into an oxygen donor, increasing the formation of carbon dioxide during the combustion reaction with hydrocarbons through the mass balance of air and fuel.
To achieve this objective, the present invention comprises the following steps:
In step a), the water is preferably demineralized and deionized. The alcohol is preferably selected to allow oxidation of peer groups C2 and C4. Linear or branched alcohols can be used. It is noteworthy that branched alcohols require an additional step to eliminate acids from their respective alcohols.
Preferably, ethyl, propyl, butyl, allyl and hexyl alcohol are used. Longer-chain alcohols, especially allyl, are used due to their natural process resulting from the fermentation of alcohol into sugar, generating by-product alcohols of the type of isopropanol, n-propanol, isobutanol, amyl, isoamyl, 2-ethylhexanol, n-heptanol, isoheptanol and n-octanol. Thus, its dispersion in water favors the formation of butyl alcohol, which, like ethyl alcohol, will produce carbon dioxide in the combustion chamber during the combustion reaction.
Alcohol, ideally, is pure and anhydrous, with its purity in the range of at least 99.96%. In another embodiment, the alcohol can be free of water. The mixture comprises between 1 and 4% water and 99 to 96% alcohol. This mixture is homogenized by the action of a piston, with pressures between 300 and 500 atm. Homogenization occurs with particles with a maximum size in the range of 130 nm, preferably between 110 and 130 nm. The normal particle size distribution predicts 90% of the particles to be between 110 and 130 nm in this mixture.
The concentration of the particles is controlled using a particle size meter as well as their attraction potential, Zeta. The Zeta attraction potential, also called the electrokinetic potential, is the potential in the slip/shear plane of a colloid particle moving under an electric field. The electric potential of a surface is the amount of work that needs to be done to bring a positive unit charge from infinity to the surface without any acceleration. The Zeta attraction potential reflects the potential difference between the EDL (electric double layer) of electrophoretically mobile particles and the dispersant layer surrounding them in the slip plane. The Zeta attraction potential is measured by a Zetasizer, considering particles up to 0.1 nm.
Particle size is relevant not only for homogenization, but also for the proper functioning of the product. The smaller the size of the alcohol molecules, the more the “protection” of these molecules by water occurs. Small chain alcohols are preferable as the prevent the formation of acetic acid during the super oxidation step, due to their size and the presence of water.
In step b), when this mixture of alcohol and water is homogenized and subjected to ultrasound radiation, the alcohol and water molecules “explode” and function as a means of dispersion, where, due to the high molecular organization provided by the ultrasound waves, the formation of an organization analogous to a colloidal nanometric dispersion occurs. This suspension occurs momentarily and for a short period.
The particle size used in the colloidal nanometric dispersion is in the range between 60 and 120 nm, preferably between 80 and 100 nm.
The ultrasound frequency is expressly defined by the alcohol used. Ethyl alcohol uses a frequency between 20 and 30 kHz, propyl alcohol uses a frequency between 30 and 40 kHz, butyl alcohol uses a frequency between 40 and 50 kHz, allylic alcohol uses a frequency between 60 and 70 kHz, and hexyl alcohol uses a frequency between 70 and 90 KHz.
The time of exposure to ultrasound ranged from 20 to 40 minutes in solution, proportional to the energy generated by the previously mentioned ultrasound.
By increasing the molecular activity, it is possible to increase the electronic charge of oxygen as a function of the time of exposure to the super oxidant environment. In a preferred configuration, in step c), hydrogen peroxide is added to the mixture, as a super oxidant medium. Hydrogen peroxide is intended to increase the activity of oxygen with alcohol.
The hydrogen peroxide used varies from 20 to 70 volumes and its concentration in the process varies between 0.5 and 5%
The present invention works in the irradiation step in a super oxidant environment with pH between 6 and 8. In step d), the action of radiation in bands between 0 and 500 nm, more specifically between 100-300 nm, in a super oxidant environment, allows the displacement of oxygen molecules starting from the breaking of the hydroxyl bond.
The system is exposed to UV radiation between 1 and 5 minutes, maintaining the same energy already suggested.
In this system, with the increase of electronic load, it is necessary to define the exposure of this load through stability. For stability, self-organization under the action of pressure and under the action of an acid medium with excess of metal ions, under the action of two electrodes, one anode and one cathode, are essential factors. Self-organization occurs after the actions of wave frequencies and under homogenization action, leading to stability of maximum concentration of particle sizes in the same nanometer range in more than 90%, previously they were between 50 and 65%. This system known as self-organization is due to the homogeneity of the particle size after wave frequency action and homogenization under controlled pressure.
After this step, the electrochemistry takes place, in step e). Cathode and anode are added to the mixture, namely platinum and palladium.
To this principle of electrolysis, a slightly acid medium is established, having its pH between 3.5 and 6.5, preferably between 4.5 and 6.2, even more preferably between 4.5 and 5.5. The charge used is a 1.5 V battery.
Molecular sieve modified in an acid system, until the pH is maintained, this reaction of the sieve in an acid medium takes between 6 and 8 hours before being used in the process. The composition of the acid medium in the electrolysis described here in the present invention, configures the action of an electricity charge, in an ionic solution, of metallic ions in a type of bed in the form of a membrane, and these ions become extremely active and the present invention has its effective conclusion when the monodisperse increase in the anode. Organic acids such as oxalic, oleic, and modified phosphoric are preferably used.
Metal ions are at least one of zinc, iron, copper, nickel, platinum, and palladium.
The membrane is of the adsorber type, of the molecular sieve type, with the presence of palladium and platinum.
The electrical charge developed by the oxidation reaction is greater than −35 mV, preferably between −35 and −50 mV, and with polarity greater than 20, preferably between 22 and 35 mV.
In some countries, where gasoline or fuel in general is heavily filtered, it is common to use metals to increase the fuel's octane rating, serving as a catalyst during combustion. The role of metals in this process is completely different, being even removed before combustion.
In step f), microwave radiation is used to remove the metals used for electrolysis. Exposure to radiation in the microwave range is carried out between 10 and 15 minutes.
Said metals or metal ions are used only as catalysts and cannot form part of the product. The presence of metal particles can clog injector nozzles, in addition to causing their deposition on top of the pistons, disturbing the reaction, in addition to increasing the mass of the piston (mobile mass), which would cause loss of combustion efficiency.
Radiation in the microwave spectrum promotes segregation of the metal, which is then filtered out of the additive. Each metal used requires a specific microwave range for segregation. Equipment: Anton Paar Multiwave 3000 microwave oven—Particle size in nm/Power in Watt. The applied power varies depending on the concentration of metal ions present in the solution. The wavelength varies depending on the concentration of metals present in the solution.
For copper with a particle size in the range of 220 nm, 700 W are used. In the case of iron, with a particle size in the range of 262 nm, 950 W are used. In relation to manganese, with a particle size in the range of 254 nm, 350 W are used. For nickel, with a particle size in the range of 235 nm, 610 W are used. In the case of zinc, with a particle size in the range of 206 nm, 200 W are used. Regarding palladium, with particle size in the range of 270 nm, 240 W are used. For platinum, with particle size in the range of 265 nm, 500 W are used.
In step g), the atomization of the solution is carried out in the middle of alcohols with high molecular mass to avoid its evaporation, in which the molecular weight is between 700 and 3000 Dalton. 2-ethylhexanol alcohol, nonyl alcohol and decyl alcohol.
The transport and storage of the product between the stages of the process described in the present invention can be carried out in containers. A person skilled in the art can discern which is the best device to transport and store the product during the stages of the present invention.
The whole process aims to increase the concentration of oxygen in combustion. In partial combustion, between 50 and 60% of conversion into CO2 effectively occurs and in complete combustion, above 85%. The combustion stoichiometry is 1:16.6. The difference with partial combustion is that when we incorporate oxygen donor agents, we reach almost complete levels of combustion, when we increase the formation of CO2 in the internal combustion chamber. The maximum efficiency of a combustion process is when we reach the ratio of 1 kg mol of air being equal to kg/mol of fuel, in this case the ideal compression ratio is diesel (16:1), gasoline (15-16:1), alcohol (20:1) and so on.
In this way, the absence of the formation of nitrous oxides causes the formation of chains of nitrous hydrocarbons, NH2—C and, in this way, the action of the antioxidant that could theoretically affect combustion, in the decrease of CO2, starts to act together with the exit of combustion gases increasing the lubricity power when in contact with metal surfaces close to combustion gas outlet areas.
The present invention clarifies that the increase in the formation of CO2 is exclusively due to the increase in the formation of Oxygen in its most active form, O−2 and not due to the complete degradation of the alcohol molecule into CO2 with the generation of electrical energy. The present invention, through the definition of the particle size, the time of action of the wave frequency in a super oxidant medium of the promotion of the stability of the electronic charge in a slightly acid medium, allows to present the means of initiation and propagation of the increase of CO2 formation together with the fuel's hydrocarbon chain, causing the termination of the reactions to be due to the greater presence of oxygen and the greater amount of CO2 formed in the combustion chamber.
The electronic charges formed are specific to the nanometric monodisperse so that together with the air inlet it increases the formation of carbon dioxide, unbalances and does not allow the formation of nitrous oxides, alters the stoichiometry of the air-fuel reaction by directly increasing the volume of oxygen and thus increase the repulsion of the combustion medium the interferences of nitrogen in these reactions.
Due to the fact that the process is associated with the particle size of the dispersion, is associated with irradiation in a super oxidizing environment and the donation of ions in an electronic medium for the controlled increase in the formation of O−2, we have control of the emission of pollutants from the chamber of combustion such as NOx and COx, the non-formation of particulate matter due to the proper adjustment of the air+fuel reactions by increasing oxygen in the fuel and thus, we have the data below for the comparison of combustion gases without the action of the oxygen donating agent of the present invention, with different types of fuels, different types of diesel and OTTO combustion cycles, and consequently the measurements showing the reduction of pollutants proportionally to the increase in the formation of carbon dioxide in the combustion chamber, the lowest consumption of fuel.
Due to this resistance, promoted by the particle size, the increase in the formation of CO2 by the oxygen donation of the present invention, the results demonstrate lower consumption, in the proposed driving conditions as well as in the adverse controlled conditions involving the tested engines.
For the study of the product, tests were performed, and for this, the cell detector was set at 90 degrees, and the cell temperature was set at 25° C. The thermal equilibrium of the samples was found before the analysis.

The present invention had its result verified in tested equipment, which were duly measured in accordance with current ABNT and Inmetro standards. The fuels used are those of normal daily use for all users, and as the engines tested are within the emission norms and use well-known standards such as EURO 4 and EURO 5.
Remembering that this reaction is added to the formation of water, responsible for the direct action of pressure on the combustion system.
The sequence of energy formed the increase in the presence of electronic charges of oxygen in the medium are the reason for the increase in the formation of CO2.
We reinforce that the present invention does not transform into its electrolysis action the nanometric dispersion duly irradiated when the temperature and pressure action directly into CO2, but an oxygen donation agent to increase the formation of CO2 together with the air and the hydrocarbons of the fuel.
The present invention in the proposed range of pH and in the time of irradiation and subsequent electrolysis and in function of the metal ions in solution promote, for the most part, above 75% of the reactions of hydrated electrons with oxygen, forming O−2, in the present invention due to metal ions in an acidified mineral system, reactions reach more than 80%. Keeping the pH in the range of 5 to 5.5.
In the combustion chamber, efficiency is greater due to the hydrogen atoms and hydroxyl radicals of the alcohol molecule tending to react with the saturated organic part of the fuel.
The present invention, as already described, allows the reaction of nitrogen compounds with hydrated compounds, thus generating NH2.
The suitable concentration of the present invention as a function of its particle size in the range of 80 to 100 nm is of the order of 1:10,000 on fuels, or 0.001% or 100 ppm. Such concentration promotes a greater balance when combustion is started and better performance.
We consider all the reactions in the formation of the O−2 radical, as first order, it is fundamental that the reaction of irradiation via UV in a super oxidant solution, works with pure water, in amounts inferior to 10%.
That the first reaction is the increase of the hydroxyl group and then the increase in the formation of O−2, so when the reaction is carried out under pressure and temperature in the combustion chamber, we will obtain a greater amount of oxygen ions in contact with the oxygen in the air forming with the fuel higher amount of CO2.
Briefly, the process in question involves particle size reduction, followed by irradiation in a super oxidant solution, followed by immersion in a slightly acid mineral solution and electrolysis in a slightly acid ionic solution.
The product resulting from this process is an oxygen donor solution when associated with the pressure and temperature present in internal combustion systems such as those present in mechanical energy generation systems.
The present invention reveals new intermolecular forces (dipole-dipole) as well as hydrogen bonds that incorporate O2(−2) (negatively charged −2 oxygen) into the fuel. The mechanism of action occurs at the beginning of the combustion process when the fuel composed of aromatic, naphthenic and saturated chains begin their reactions. Part of the chains start their reactions from 90° C. to temperatures above 250° C., in the highest concentration of saturated and naphthenic chains.
The incorporation of oxygen with negative charge −2 together with the fuel, considering the mass balance with unaltered air, means that the present invention increases the amount of oxygen in the combustion reaction, enhancing the formation of CO2 and, therefore, increasing the energy produced during combustion. As this will increase the efficiency of the oxidation process, less CO and unburned hydrocarbons are produced during combustion.
At the same time, due to its high negative charge (polarity), the fuel mixed with the present invention repels nitrogen molecules during combustion, until the moment when the nitrogen molecule in the air begins to form nitrous hydrocarbons, NH2 together with the fuel molecule. Oxygen and NH2 are increasing lubricity during combustion.
The increased formation of CO2 in the combustion chamber reduces fuel consumption and consequently reduces emissions of CO2/km. The increase in the reaction of CO+½O2⇒CO2 with the formation of water vapor is increasing the system pressure.
This CO2 concentration process reduces the formation of NOx by up to 70%, reduces consumption by up to 15% and reduces the formation of particulate matter by more than 70%.
The process of the present invention results in an ionized nanometer colloidal dispersion that, when mixed with liquid fossil fuel, creates a nanometer colloidal dispersion of fuel, with hydrocarbons generating macromolecules.
The present invention transfers the polarity to liquid fuel. In the production process, the polarity and size of the particles are controlled, in addition to creating resistance to the pressures inside a combustion chamber. In this way, the present invention results in a product with electronic stability.
With their new charge, the fuel molecules repel the nitrogen molecules during the combustion reaction. Nitrogen does not take as much energy from the combustion reaction through the endothermic process of creating NOx, and combustion releases more useful working energy and less harmful emissions.
In complete combustion, if all the carbon in the fuel is burned and transformed into CO2, all the hydrogen is transformed into H2O, and all the sulfur (if present) is transformed into SO2.
In incomplete combustion, the result of combustion still has unburned fuel or components such as C, H2, CO or OH.
Reasons for incomplete combustion are insufficient oxygen, insufficient mixing in the combustion chamber during mixing of fuel and oxygen, and dissociation at high temperatures.
Oxygen has a much greater tendency to combine with hydrogen than with carbon. That said, the hydrogen in the fuel is normally completely transformed, generating H2O.
The stoichiometry of octane combustion occurs as follows:
Starting from reaction (I), it is possible to determine the masses of the reaction. The molecular mass of air (M_air) is 28.97 kg/kmol, while the mass of octane (M_octane) is 114 kg/kmol. Air (AC moles) is composed by the sum of the amount of moles of oxygen and hydrogen which results in 59.5. The fuel ratio (AC mass) is 15.12 moles.
In fuel oxidation, in which hydrogen, oxygen, gasoline (C8H18), diesel (C12H26) and ethanol (C2H6O) are used. Combustion does not occur with pure oxygen. In combustible air, we consider 21% oxygen and 79% nitrogen, resulting in a ratio between nitrogen and oxygen equivalent to 3.76. Resulting in a molar mass of air of 28.97 kg/kmol.
The luminosity test was carried out under the following conditions: engine speed: 1200 rpm; injection duration: 3500 μs (input), 3437 μs (actual); injection pressure: 180 MPa; nozzle configuration: 2×0.110 mm×140°; ducts: D2L12G1.6 vs. D2L12G3
vs. none; moment of initiation of combustion: top dead center (0 CAD); dilution: 21 and 16% of moles of oxygen; absolute pressure in the intake manifold: 2.0 bar; intake manifold temperature: 90° C.; cooling temperature: 90° C.; start of injection (crankshaft angle values after top dead center) for 16% oxygen: conventional diesel combustion: −2.69, D2L12G3δ: 3.55 and D2L12G1.6δ: −3.52; start of injection (crankshaft angle values after top dead center) for 21% oxygen: conventional diesel combustion: −1.66, D2L12G3δ: −2.52 and D2L12G1.6δ: −2.33.
Liquid fuel 2 and fuel vapor and air mixture 3 then enter duct 4. Duct 4 is configured to direct liquid fuel 2 and fuel vapor 3 into the combustion chamber.
Upon entering the combustion chamber, given its pressure characteristics, there is the self-ignition zone 5. After the self-ignition zone 5, combustion takes place.
In combustion, it is possible to verify the formation of three zones. A zone with a rich combustion product or mixture 6, flame diffusion 8 and a thermally unproductive zone 7.
