Abstract

A method and catalysts and fuel processing apparatus for producing a hydrogen-rich gas, such as a hydrogen-rich syngas are disclosed. According to the method, a CO-containing gas, such as a syngas, contacts a platinum-free ruthenium-cobalt water gas shift (“WGS”) catalyst, in the presence of water and 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 platinum-free ruthenium-cobalt water gas shift catalyst formulated from:
