Apparatus for the selective oxidation of carbon monoxide in a hydrogen-containing gas mixture

摘要

A method and apparatus for selectively oxidizing the carbon monoxide present in a mixture of gases, including hydrogen, to carbon dioxide is disclosed. Oxygen or an oxygen-containing gas mixture is introduced at locations along the latter portion of the reaction chamber in an isothermal reactor to selectively oxidize the carbon monoxide to carbon dioxide and to suppress the reverse to water-shift reaction, which produces carbon monoxide and water from carbon dioxide and hydrogen.
