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 environmentally harmful byproduct gases.

摘要:
A method of producing hydrogen gas from a reaction of an organic substance having multiple alcohol functionality with a base. Hydrogen can be produced in a reaction of a base with an organic substance having multiple alcohol functionality that may proceed through the formation of a bicarbonate or carbonate compound as a byproduct. In some embodiments, the reaction may occur in the presence of water. The preferred organic substances include diols, triols, and higher order alcohols. Non-cyclic (linear or branched) organic substances having multiple alcohol functionality are among the preferred reactants. The instant base-facilitated hydrogen-producing reactions are thermodynamically more spontaneous than the corresponding conventional reformation reactions of the organic substances and can produce hydrogen at less extreme reaction conditions. The preferred reactants further include low volatility organic substances having multiple alcohol functionality. Such reactants permit the efficient formation of hydrogen in a liquid phase system and enable a continuous reaction capability in the liquid phase without the need to condense volatilized reactant.

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 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.
