Abstract:
1. A process for oxidizing carbon monoxide with oxygen to carbon dioxide comprises: (a) contacting a feed stream comprising carbon monoxide, hydrogen and oxygen with a composition comprising platinum and iron in a contacting zone at an operating temperature in the range of from about 60° C. to about 100° C., so as to produce a product stream comprising less carbon monoxide than said feed stream, for a prolonged period of time until said composition is at least partially deactivated thereby forming an at least partially deactivated composition; (b) increasing the temperature of said contacting zone such that said feed stream is contacted with said at least partially deactivated composition at a regeneration temperature in the range of from 150° C. to 250° C. to thereby form an at least partially regenerated composition; and (c) decreasing the temperature of said contacting zone such that said feed stream is contacted with said regenerated composition at said operating temperature in the range of from about 60° C. to about 100° C.
