ABSTRACT:
Use of a catalyst composition comprising a metal selected from the group consisting of ruthenium, rhodium, nickel and combinations thereof, on a support selected from the group consisting of a beta-zeolite, mordenite and faujasites, is taught for carbon oxide methanation reactions for fuel cells. Specifically, when a mixture of gases containing hydrogen, carbon dioxide, carbon monoxide, and water is passed over the catalyst in a reaction zone having a temperature below the temperature at which the shift reaction occurs and above the temperature at which the selective methanation of carbon monoxide occurs, the catalyst efficiently facilitates the selective hydrogenation of carbon monoxide using H2that is present in the reformate and reduces the concentration of the CO to levels equal to or less than about 50 ppm and demonstrates a carbon monoxide (CO) methanation selectivity of greater than about 50%.
