摘要:
A base-facilitated reaction for the production of hydrogen from biomass or component(s) thereof. Hydrogen is produced from a reaction of naturally occurring organic matter with a base to form a bicarbonate or carbonate compound as a by-product. The base-facilitated hydrogen-producing reactions are thermodynamically more spontaneous than conventional-type reformation reactions and are able to produce hydrogen gas at less extreme reaction conditions than conventional-type reformation reactions. The preferred reactants are biomass, components of biomass, and mixtures of components of biomass. Especially preferred are base-facilitated reactions in which hydrogen is produced from carbohydrates or mixtures of carbohydrates, include monosaccharides, disaccharides, polysaccharides, and cellulose. The instant reactions can occur in the liquid phase or solid.

摘要:
A method of producing hydrogen gas from a reaction of carbon monoxide with a base. Hydrogen is produced in a reaction of a base with carbon monoxide that proceeds through the formation of a bicarbonate or carbonate compound as a by-product. In some embodiments, the reaction may occur in the presence of water and may produce carbon dioxide as a by-product. The instant base-facilitated hydrogen-producing reactions are thermodynamically more spontaneous than the water-gas shift reaction and are able to produce hydrogen gas from carbon monoxide at greater reaction rates than is possible with the water-gas shift reaction. Carbon monoxide in a purified or unpurified state or as a component within a mixture of gases is suitable for use in the instant invention. Metal hydroxides are the preferred base reactant. The base reactant can be in the solid phase, molten phase, liquid phase or solution phase.
摘要:
A base-facilitated reformation reaction. Hydrogen is produced from a reaction of an organic substance with a base to form bicarbonate ion or carbonate ion as a by-product. The base-facilitated reformation reactions are thermodynamically more spontaneous than conventional reformation reactions and are able to produce hydrogen gas at less extreme reaction conditions than conventional reformation reactions. In one embodiment, the instant base-facilitated reactions produce hydrogen gas from an organic substance at a lower temperature than is possible for the production of hydrogen gas from the organic substance in a conventional reformation reaction. In another embodiment, the instant base-facilitated reformation reactions produce hydrogen gas from an organic substance at a faster rate at a particular temperature than is possible from the conventional reformation reaction of the organic substance. In yet another embodiment, a reformation reaction is made spontaneous in the liquid phase by running the reaction at an elevated pressure. The preferred organic substances of the instant invention are hydrocarbons having four or more carbon atoms per molecule or mixtures thereof that are available from fuels such as gasoline, bio-diesel, diesel or other petroleum distillates or by-products.

摘要:
A process for producing hydrogen gas from hydrocarbon and oxygenated hydrocarbon compounds. The process includes combining a hydrocarbon or oxygenated hydrocarbon compound with a base to form a mixture that undergoes a reaction to produce hydrogen gas. The reaction mixture optionally includes water and/or a catalyst. In a preferred embodiment, hydrogen production occurs from methanol in the liquid phase without the production of environment harmful by-product gases.

摘要:
A base-facilitated process for producing hydrogen. Hydrogen is produced from a reaction of carbonaceous matter with a base and water, preferably through the formation of a bicarbonate or carbonate by-product. The base-facilitated hydrogen-producing reactions are thermodynamically more spontaneous and are able to produce hydrogen gas at less extreme reaction conditions than conventional reformation or gasification reactions of carbonaceous matter. In another embodiment, the instant reactions permit the production of hydrogen from carbonaceous matter without the production of carbon dioxide or carbon monoxide. In a preferred embodiment, the carbonaceous matter is coal or a derivative thereof.
