Hydrogen-rich gas is produced by reacting gas mixtures comprising CO and H2O in a reactor containing an improved unsupported catalyst comprising an alkali-metal promoted partially reduced mixture of at least one copper uranate and at least one oxide of copper. The weight percent uranium present in the activated catalyst, based on total weight of catalyst composition, is in the range of over 50 to about 90.

A process for the production of a hydrogen-containing gas comprising: (1) introducing a feed gas mixture comprising CO and H2O at a temperature in the range of about 375°to 1500°F. and a pressure in the range of about 1 to 300 atmospheres into a reaction zone containing an unsupported catalyst comprising an alkali-metal promoted partially reduced mixture of at least one copper uranate and at least one oxide of copper; wherein at least 30 to about 80 weight percent of the copper in the catalyst is present in the metallic state and of the remainder of the copper 85 to 100 weight % is in the form of copper uranate and the balance of the copper if any is present in the form of copper oxide; and the total weight percent of uranium present in said catalyst basis total weight of said catalyst composition is in the range of over 50 to about 90 weight percent; (2) converting CO in said gas mixture into H2+CO2 by reacting CO in said reaction zone with H2O; and (3) removing a H2-rich gas from said reaction zone.
