Abstract
Disclosed in a catalyst which enables to reduce the carbon monoxide concentration in a product gas to 5 ppm by volume or less when carbon monoxide in a raw material gas containing hydrogen and carbon monoxide is selectively oxidized. The catalyst comprises a support of an inorganic oxide and ruthenium loaded thereon, and the relative loading depth X(Ru) of ruthenium in the radial direction in a redial cross-section of the catalyst satisfies the requirement defined by the following formula (1)X(Ru)≧15  (1).
