ABSTRACT:
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.
