HYDROGEN COMBUSTION CATALYST AND PROCESS FOR PRODUCTION THEREOF, AND HYDROGEN COMBUSTION METHOD

Document Type and Number:

WIPO Patent Application WO/2011/083833

Kind Code:

A1

Abstract:

Disclosed is a hydrogen combustion catalyst which comprises a carrier comprising an inorganic oxide and a catalyst metal supported on the carrier, and which is characterized in that a functional group having, attached to the terminal thereof, at least one alkyl group having 3 or less carbon atoms is bound to a hydroxy group present on the surface of the carrier through substitution. The functional group to be attached to the hydroxy group present on the surface of the carrier is preferably an organosilane. The hydrogen combustion catalyst can retain the activity thereof even when a hydrogen-containing gas to be treated has a moisture content equal to or lower than the saturated water vapor quantity and the hydrogen combustion catalyst is used at around room temperatures of 0 to 40°C.
