Abstract: Hydrogen is produced by reacting carbon monoxide with steam at a temperature of at least 200.degree. F. in the presence of a supported catalyst containing: (1) at least one alkali metal compound derived from an acid having an ionization constant below 1 .times. 10.sup.-3, (2) a metallic hydrogenation- dehydrogenation material, and (3) a halogen moiety.

The halide constituent is present in amounts in excess of about 0.01 weight %, based on total catalyst. A preferred catalyst composition comprises potassium carbonate, a mixture of cobalt and molybdenum oxides and combined chlorine contained on an alumina support.

Abstract: Hydrogen is produced by the combustion of carbon with air to produce a combustion gas effluent containing carbon dioxide and nitrogen. The carbon dioxide is separated and reacted with carbon to produce carbon monoxide. The resulting produced carbon monoxide is then reacted with steam to produce carbon dioxide and hydrogen and the resulting produced hydrogen separated. The carbon utilized for the production of hydrogen may be obtained by the thermal decomposition of hydrocarbons to yield carbon and gaseous hydrogen or the carbon utilized in this process may be obtained from a solid carbonaceous fuel, such as coal or coke or the like.

Abstract: This is a continuous process for producing hydrogen-rich gas. Successive beds of water-gas shift conversion catalysts of differing properties are employed in a shift converter to achieve an economical balance between catalyst activity and catalyst life. For example, a comparatively small fixed bed of highly active low temperature water-gas shift conversion catalyst may be loaded on top of a fixed bed of rugged low cost moderately active high temperature water-gas shift catalyst. A CO-rich gas and H.sub.2 O are introduced into the bed of low temperature shift catalyst where reaction takes place. The partially reacted gas stream leaves the bed of low temperature shift catalyst and is introduced into the bed of high temperature catalyst at a suitable temperature for triggering off therein the water gas shift reaction without the additon of heat from an external source. By this means it may be possible to produce hydrogen-rich gas with high conversions of CO to CO.sub.

Abstract: A process for reacting carbon monoxide with steam at temperatures below 300.degree.C. over a catalyst comprising the product of reducing partly the co-precipitated oxides of copper and zinc and at least one further metal selected from the metals of Groups II to V of the Periodic Table whose oxides are usable as catalyst supports.

Abstract: There is disclosed a process for the preparation of hydrogen-rich gas by passing a gas mixture containing carbon monoxide and water vapor over a sulfided catalyst which includes nickel and/or cobalt, molybdenum and aluminum with the aluminum being present in an amount of from 0.1 to 1.0 part of aluminum per part of nickel and/or cobalt on a weight basis. The catalyst is prepared by impregnating an alumina carrier with one or more solutions of compounds of the catalysts in which at least 40%w of the aluminum that is used is added to the carrier by co-impregnation with the nickel and/or cobalt.

Abstract: A process for the production of hydrogen/deuterium-containing gas in which the enriched condensate obtained from the production of a hydrogen/deuterium-containing gas mixture is collected and subjected to a direct exchange of isotopes with the feedsteam admitted to the process. Such condensate can be brought into direct exchange of isotopes with the gas water vapour mixture within the process, viz. ahead of the CO conversion section. The exchange of isotopes may be performed according to the counter-current principle. If it is intended to maintain in the hydrogen/deuterium-containing gas a certain definite content of water vapour whose phase condition is superior to the condition achieved when using normal cooling water, this gas, at least 0.6 kg/m.sup.3 of gas, is subjected to an exchange of isotopes with the water fed additionally into the process.

Abstract: A method of obtaining hydrogen from water in a multi-stage circulatory process avoids the need to use solid inorganic salts as auxiliary products by using only gases and liquids in the reaction stages. Carbon monoxide is reacted catalytically with steam producing carbon dioxide and hydrogen; the carbon dioxide is reacted with steam and sulphur dioxide to give sulphuric acid and carbon monoxide; the sulphuric acid is split into sulphur trioxide and steam; the sulphur trioxide is dissociated into oxygen and sulphur dixoide. The CO and SO.sub.2 are fed back into the process, and hydrogen and oxygen obtained as end products.
