| abstract |
Disclosed are methods and catalysts and fuel processors for producing hydrogen-enriched gases, such as hydrogen-enriched syngas. According to the method, a CO-containing gas such as syngas is contacted with a platinum-free ruthenium-cobalt water gas shift (WGS) catalyst in the presence of water, preferably at a temperature not exceeding 450 ° C., and a hydrogen-enriched syngas. Produces hydrogen-enriched gas. Also, a) Ru, its oxides, or mixtures thereof b) Co, Mo, their oxides, or mixtures thereof, and c) Li, Na, K, Rb, Cs, Ti, Zr, Cr, Fe, La A platinum-free ruthenium-cobalt water gas shift catalyst is disclosed that is formulated from at least one of Ce, Eu, their oxides, and mixtures thereof. The WGS catalyst can be supported on a support such as any one constituent or combination of alumina, zirconia, titania, ceria, magnesia, lanthania, niobia, perovskite, silica clay, yttria, and iron oxide. A fuel processor including such a water gas shift catalyst is also disclosed. |
