Abstract:

A method for generating energy and/or fuel from the halogenation of a carbon-containing material and/or a sulfur-containing chemical comprises supplying the carbon-containing material (e.g., coal, lignite, biomass, cellulose, milorganite, methane, sewage, animal manure, municipal solid waste, pulp, paper products, food waste) and/or the sulfur-containing chemical (e.g., HS, SO, SO, elemental sulfur) and a first halogen-containing chemical to a reactor. The carbon-containing material and/or the sulfur-containing chemical and the halogen-containing chemical are reacted in the reactor to form a second halogen-containing chemical and carbon dioxide, sulfur and/or sulfuric acid. The second halogen-containing chemical is dissociated (e.g., electrolyzed) to form the first halogen-containing chemical and hydrogen gas (H). The first halogen-containing chemical can be Brand the second halogen-containing chemical can be HBr. Any carbon dioxide formed during reaction can be directed to a prime mover (e.g., turbine) to generate electricity. Any ash and/or sulfur formed can be removed. In some cases a sulfur-containing chemical can be supplied to the reactor with the carbon-containing material.

US Classification:

204 98

Abstract:

Disclosed are both an apparatus and method for the radiation-augmented electrolytic production of alkali metal hydroxide, molecular halogen, and hydrogen. Reduction of electrical energy requirements is achieved by using radiation to activate photo-sensitive metallic hexahalide ions, which reduces the electrolysis electrode potential. By utilizing radiation-augmented electrolysis, the conventional halogen oxidation reaction is replaced by oxidation of a metallic hexahalide, which occurs at a lower overvoltage and smaller reversible cell potential. Radiant energy thus replaces electrical energy for the production of alkali metal hydroxide, molecular halogen, and hydrogen. Since the action of radiation on the oxidized form of the metallic hexahalide, in the presence of a concentrated halide ion, leads to the production of free halogen gas, the net products are not modified by use of the metallic hexahalide, but the energy requirement of the process is reduced.

International Classification:

G21C 2300

US Classification:

376323

Abstract:

A nuclear excited power system includes a gaseous core nuclear reactor through the core of which helium is passed. The helium is excited by the high energy radiation from the nuclear reactor and is coupled to a reaction chamber wherein the high energy helium mixes with hydrogen and a halogen, such as, chlorine. The energy thus transferred to the hydrogen and chlorine causes the hydrogen and chlorine to combine to form a hydrogen chloride plasma. The high temperature, high pressure hydrogen chloride plasma drives a turbine, magnetohydrodynamic generator or other electromechanical device to form electrical and/or mechanical energy. The helium and hydrogen chloride exhaust products are separated with the helium coupled back to the reactor core. The hydrogen chloride is disassociated and coupled back to the reaction chamber.

Abstract:

A method for the joint i) abatement of emission of a "greenhouse" gas by removing carbon dioxide from an effluent and ii) manufacture of methanol by reaction of hydrogen with carbon dioxide which includes: a) reacting carbon dioxide in the effluent by flowing contact of the effluent with a bed of basic metal oxide at a temperature suitable to form a metal carbonate, b) then stopping the effluent flow after said bed has become substantially converted to the carbonate, c) heating the carbonate to a temperature suitable to release carbon dioxide, d) then mixing the released carbon dioxide with hydrogen while passing the mixture over a catalyst of another metal oxide at a suitable temperature and pressure for a reaction, and thereby forming methanol.

International Classification:

F01K 2506

US Classification:

60673

Abstract:

The present invention relates to an energy conversion system and more particularly tot he related apparatus and process. A reactor chamber is positioned with respect to a means for collecting and focussing. The focussed beam of radiation is employed to induce a reversible reaction in which the reaction products are converted into work in a work output means. Following that conversion, the reaction materials are passed through a heat sink and are recycled so that the process can be continuously operated.

US Classification:

Abstract:

Disclosed are an apparatus and method for the electrolytic, thermal, and photolytic production of hydrogen and oxygen. In the first step of the cycle a concentrated hydrohalic acid solution is electrolyzed to produce hydrogen, halogen, and dilute hydrohalic acid solution. In the second, or hydrogen halide formation and electrolyte reformation step, the halogen is reacted with steam in a gas phase thermal and photolytic process to reform the hydrogen halide and produce oxygen. An advantage of the novel reformation step is the ability to utilize a contaminated water feedstream for the production of the reusable hydrogen halide. The present invention also provides both an apparatus and method for the radiation-augmented electrolytic and thermal production of hydrogen and oxygen. Reduction of electrical and thermal energy requirements is achieved by using radiation to: (i) activate photo-sensitive metallic hexahalide ions, which reduces the electrolysis electrode potential; and (ii) energize a portion of the hydrogen halide formation reaction. By utilizing radiation-augmented electrolysis, the conventional halogen oxidation reaction is replaced by oxidation of a metallic hexahalide, which occurs at a lower overvoltage and smaller reversible cell potential.

International Classification:

F03G 600

US Classification:

6064114

Abstract:

Disclosed are an apparatus and method used to preheat a working fluid for a subsequent solar-driven dissociation reaction. The working fluid is first passed through a blackbody receiver where it absorbs thermal energy, and is subsequently exposed to direct solar radiation. The present invention allows the working fluid to absorb relatively large amounts of solar energy at elevated temperatures, while the blackbody absorber remains at a relatively low temperature, thus minimizing energy losses through reradiation and enhancing the efficiency of the overall energy exchange.

Abstract:

A receiver is described for a solar dynamic power generator. The generator has a heat cycle engine to generate power. The receiver has a working fluid including a radiant eneryg absorber selected from halogens and interhalogens. The receiver also has a hollow, cylindrical containment for containing the working fluid having a first end, a second end and an inner wall. A hollow, cylindrical member, is disposed within the containment. The cylindrical member has an inner wall an and outer wall, and defines a toroidal working fluid flow space within the containment and a receiving space within the inner wall of the cylindrical member. A window is disposed in the first end of the containment for admitting solar radiation in the receiving space and heating working fluid contained in the receiving space. The heated working fluid in the receiving space travels toward the first end of the containment. A latent heat storing material is disposed in the flow space between the outer wall of the cylindrical member and the inner wall of the containment for storing heat absorbed by the working fluid in the receiving space.
