Title:
CATALYST FOR REDUCING CARBON MONOXIDE CONCENTRATION
Document Type and Number:
WIPO Patent Application WO/2008/075761
Kind Code:
A1
Abstract:
Disclosed is a catalyst which enables to reduce the carbon monoxide concentration in
a product gas to 5 volume ppm or less when carbon monoxide in a raw material gas containing
hydrogen and carbon monoxide is selectively oxidized. The catalyst comprises
a carrier composed of an inorganic oxide and ruthenium loaded onto the carrier,
and the relative loading depth X(Ru) of ruthenium in the radial direction of a
catalyst section along the radial direction satisfies the condition represented by
the following formula (1). X(Ru) ≥ 15 (1)
