METHOD FOR SELECTIVE OXIDATION OF CARBON MONOXIDE IN HYDROGEN- CONTAINING STREAM Russian patent published in 2005 - IPC

FIELD: selective oxidation of carbon monoxide in hydrogen-containing stream.

SUBSTANCE: invention relates to method for selective oxidation of carbon monoxide to carbon dioxide in raw material containing hydrogen and carbon monoxide in presence of catalyst comprising platinum and iron. Catalyst may be treated with acid. Certain amount of free oxygen is blended with mixture containing hydrogen and carbon monoxide to provide second gaseous mixture having elevated ratio of oxygen/carbon monoxide. Second gaseous mixture is brought into contact with catalyst, containing substrate impregnated with platinum and iron. Carbon monoxide in the second gaseous mixture is almost fully converted to carbon dioxide, i.e. amount of carbon monoxide in product stream introduced into combustion cell is enough small and doesn't impact on catalyst operation characteristics.

EFFECT: production of hydrogen fuel for combustion cell with industrial advantages.
