Abstract
Disclosed is a catalyst for purifying emissions from compressed natural gas vehicles through oxidation, comprising platinum and palladium, as catalytically active ingredients, supported on a support system including a first palladium-impregnated alumina, a second platinum-impregnated alumina, a composite ceria, and a nickel oxide and loaded on a metal or ceramic carrier. The catalyst shows an excellent conversion rate, thus having great economic and technical advantages over conventional catalysts.
