A method and catalysts for producing a hydrogen-rich syngas are disclosed. According to the method a CO-containing gas contacts a water gas shift (WGS) catalyst, optionally in the presence of water, preferably at a temperature of less than about 450° C. to produce a hydrogen-rich gas, such as a hydrogen-rich syngas. Also disclosed is a water gas shift catalyst formulated from:a) Pt, its oxides or mixtures thereof;b) Ru, its oxides or mixtures thereof; andc) at least one of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Sc, Y, Ti, Zr, V, Mo, Mn, Fe, Co, Rh, Ir, Ge, Sn, Sb, La, Ce, Pr, Sm, and Eu. Another disclosed catalyst formulation comprises Pt, its oxides or mixtures thereof; Ru, its oxides or mixtures thereof; Co, its oxides or mixtures thereof; and at least one of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Sc, Y, Ti, Zr, V, Mo, Mn, Fe, Rh, Ir, Ge, Sn, Sb, La, Ce, Pr, Sm, and Eu, their oxides and mixtures thereof. The WGS catalyst may be supported on a carrier, such as any one member or a combination of alumina, zirconia, titania, ceria, magnesia, lanthania, niobia, zeolite, perovskite, silica clay, yttria and iron oxide. Fuel processors containing such water gas shift catalysts are also disclosed.

What we claim is: 1. A catalyst for catalyzing the water gas shift reaction consisting essentially of:a) between about 0.01 wt. % to about 10 wt. % of Pt, its oxides or mixtures thereof;b) between about 0.01 wt. % to about 10 wt. % of Ru, its oxides or mixtures thereof; andc) at least one member sel
What we claim is: 1. A catalyst for catalyzing the water gas shift reaction consisting essentially of:a) between about 0.01 wt. % to about 10 wt. % of Pt, its oxides or mixtures thereof;b) between about 0.01 wt. % to about 10 wt. % of Ru, its oxides or mixtures thereof; andc) at least one member selected from the group consisting of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Sc, Y, Ti, Zr, V, Mo, Mn, Fe, Co, Rh, Ir, Ge, Sn, Sb, La, Ce, Pr, Sm, and Eu, their oxides and mixtures thereof,wherein the catalyst is supported on a carrier comprising at least one member selected from the group consisting of alumina, zirconia, titania, ceria, magnesia, lanthania, niobia, zeolite, perovskite, silica clay, yttria, iron oxide, and mixtures thereof, andthe catalyst consists essentially of between about 0.01 wt. % to about 10 wt. %, with respect to the total weight of all catalyst components plus the carrier, of Fe, Co, Rh, and Ir, their oxides and mixtures thereof, respectively, wherein said Fe, Co, Rh, and Ir are selected from c) above.
