Abstract
Hydrogen is produced by reaction of carbon monoxide or gases containing carbon monoxide with steam at below 250 DEG C. in contact with catalysts prepared by coprecipitation of a sparingly water-soluble or insoluble compounds of, copper and aluminium together with chromium compounds and/or manganese compounds or by precipitation of compounds of copper and chromium and/or manganese on to an oxide or hydroxide of aluminium and subsequent reduction at below 250 DEG C., and in which the weight ratio of copper to aluminium is from 1:1 to 20:1. The gas to be converted may be obtained from the cracking o gaseous or liquid hydrocarbons and the conversion may be at 160-200 DEG C. at atmospheric or super-atmospheric pressure, e.g. at 5-35 atmospheres. The catalysts may have weight ratio of copper to chromium and/or manganese from 100:0.5 to 100:24. When the insoluble compounds are precipitated on the aluminium compound an aqueous suspension of aluminium hydroxide gel which has been freshly precipitated with ammonia may be used. Coprecipitation may be carried out by adding a solution of say the nitrates, sulphates or chlorides of copper and aluminium together with chromium and/or manganese to a strongly diluted solution of alkali metal hydroxide or carbonate or ammonia or ammonium carbonate at 15-95 DEG C. or by precipitation at constant pH by adding the reactants uniformly to the reactor. The precipitate is washed and dried at 105-200 DEG C. and may be calcined say at 650 DEG C. The catalyst may be pelleted or extruded before or after calcination and subsequently reduced by heating to 130-200 DEG C. in a gas containing carbon monoxide, e.g. the gas to be used in the conversion reaction.ALSO:Catalysts for the reaction of carbon monoxide or gases containing carbon monoxide with steam at below 250 DEG C are prepared by coprecipitation of a sparingly water-soluble or insoluble compounds of copper and aluminium together with chromium compounds and/or manganese compounds or by precipitation of compounds of copper and chromium and/or manganese onto an oxide or hydroxide of aluminium and subsequent reduction at below 250 DEG C and in which the weight ratio of copper to aluminium is from 1:1 to 20:1. The weight ratio of copper to chromium and/or manganese may be from 100:0.5 to 100:24.
