CARBON MONOXIDE OXIDATION CATALYST, METHOD FOR PREPARATION OF CARBON MONOXIDE OXIDATION CATALYST AND METHOD FOR PRODUCTION OF HYDROGEN-CONTAINING GAS

摘要

A catalyst for selectively oxidizing CO gas contained in a gas having hydrogen as a main component by oxygen, which comprises a carrier comprising titania and alumina and, carried thereon, ruthenium; and a catalyst for selectively oxidizing CO gas contained in a gas having hydrogen as a main component by oxygen, which comprises a carrier comprising titania and alumina and, carried thereon, ruthenium and an alkali metal and/or alkaline earth metal. A method for preparing the above catalysts which comprises carrying ruthenium or ruthenium and an alkali metal and/or alkaline earth metal on the carrier by use of a solution containing ruthenium or ruthenium and an alkali metal and/or alkaline earth metal is also provided. The catalyst exhibits high activity at a relatively high temperature.
