Process for selective oxidation of carbon monoxide in a hydrogen containing stream

摘要

Provided is a method for preparing a composition comprising admixing a substance comprising platinum and a halide and a substance comprising iron and a halide and incorporating the thus-obtained mixture into or onto an aluminum-containing compound, drying and calcining the incorporated mixture, and then admixing the calcined mixture and an aqueous ammonia solution, and drying and calcining that mixture. The thus-obtained composition is then used in a process for oxidizing carbon monoxide with free oxygen to carbon dioxide.
