PLATINUM AND RHODIUM AND/OR IRON CONTAINING CATALYST FORMULATIONS FOR HYDROGEN GENERATION

摘要

A method and catalysts for producing a hydrogen-rich syngas are disclosed. According to the method a CO-containing ags contacts a water gas shift (WGS) catalyst, in the presence of water, preferably at a temperature of less than about 450 ~C to produce a hydrogen-rich syngas. Also disclosed is a water ga s shift catalyst formulated from: a) Pt, its oxides or mixtures thereof; b) at least one of Fe and Rh, their oxides and mixtures thereof; and c) at least o ne member selected from the group consisting of Sc, Y, Ti, Zr, V, Nb, Ta, Mo, R e, Co, Ni, Pd, Ge, Sn, Sb, La, Ce, Pr, Nd, Sm, and Eu, their oxides and mixture s thereof. The WGS catalyst mas be supported on a carrier, such as any one member or a combinatino of alumina, zirconia, titania, ceria, magnesia, lanthania, niobia, yttria and iron oxide. Fuel processors containing such water gas shift catalysts are also disclosed.
