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 H2 that 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%.

Abstract: A stable water gas shift catalyst comprising platinum, rhenium and lanthanum on a high surface area rutile titanium dioxide support is described. The catalyst of the present invention is at least as efficient in converting CO to CO2 at low temperatures as the catalysts of the prior art. Further, the catalyst is about three times more stable than the catalysts of the prior art.

Abstract: A stable water gas shift catalyst comprising platinum, rhenium and lanthanum on an anatase titanium dioxide support is described. The catalyst of the present invention is at least as efficient in converting CO to CO2 at low temperatures as the catalysts of the prior art. Further, the catalyst is about three times more stable than the catalysts of the prior art.
