| abstract |
The present invention relates to a method for producing a hydrogen-enriched gas from a gas mixture containing carbon monoxide and water, such as a water-containing syngas mixture, using a nickel catalyst that contains no noble metal. It can exist even in this state. The noble metal-free water gas shift catalyst of the present invention is at least one of Ni in a supported or bulk state, and Ge, Cd, In, Sn, Sb, Te, Pb, oxides thereof and mixtures thereof. including. The present invention also relates to noble metal-free nickel catalysts that are both highly active and highly selective for hydrogen production and carbon monoxide oxidation. |
