ABSTRACT:
The invention is a catalyst composition and process for making and using the catalyst composition. The catalyst composition promotes the combustion of carbon monoxide to carbon dioxide. The catalyst composition includes an effective concentration of Group VIII transition metal oxide, an effective concentration of Group IIIB transition metal oxide, an effective concentration of Group IIA alkaline earth metal oxide, and, desirably, microspheroidal alumina. The preferred Group VIII transition metal oxide is cobalt oxide. The preferred Group IIIB transition metal oxide is lanthanum oxide. The preferred Group IIA alkaline earth metal is strontium oxide. The process is for producing a combustion promotor catalyst of carbon monoxide to carbon dioxide. The carrier for the catalyst is effective in FCC units when used on a support which is other than a mullite-containing support.
