CARBON MONOXIDE REMOVING APPARATUS FOR REDUCING AMOUNT OF CARBON MONOXIDE IN REFORMED GAS |
摘要 |
PROBLEM TO BE SOLVED: To provide a carbon monoxide removing apparatus having a catalyst useful for selectively oxidizing carbon monoxide in a hydrogen-enriched reformed gas with oxygen with which carbon monoxide in the gas can be more efficiently oxidized and the amount of carbon monoxide can be reduced. SOLUTION: The reformed gas supplied into the carbon monoxide removing apparatus 11 is first passed through a catalyst layer 12 constituted of a catalyst A in which ruthenium and platinum are supported on a porous carrier in a weight ratio of ruthenium to platinum of >=0.7 and <=9.5 and ruthenium and platinum are localized in the outer surface of the porous carrier, then the reformed gas is passed through a catalyst layer 13 constituted of a catalyst B in which ruthenium and platinum are supported in a porous carrier in a weight ratio of ruthenium to platinum of >=0.1 and <0.7 and ruthenium and platinum are localized in the outer surface of the porous carrier, and further the reformed gas is passed through a catalyst layer 14 constituted of the above catalyst A. |
