Abstract: Provided are catalyst composites whose catalytic material is effective to substantially simultaneously oxidize carbon monoxide and hydrocarbons and reduce nitrogen oxides. The catalyst composites have a two-metal layer on a carrier, the two-metal layer comprising a rhodium component supported by a first support comprising a refractory metal oxide component or a first ceria-zirconia composite; a palladium component supported by a second support comprising a second ceria-zirconia composite; one or more of a promoter, stabilizer, or binder; wherein the amount of the total of the first and second ceria-zirconia composites in the two-metal layer is equal to or greater than the amount of the refractory metal oxide component. Methods of making and using the same are also provided.

Abstract: The present invention relates to a catalytically active composition for the selective methanation of carbon monoxide in reformate streams comprising hydrogen and carbon dioxide, comprising at least one element selected from the group consisting of ruthenium, rhodium, nickel and cobalt as active component and rhenium as dopant on a support material. The catalyst according to the invention is preferably used for carrying out methanation reactions in a temperature range from 100 to 300° C. for use in the production of hydrogen for fuel cell applications.
