Abstract:
The present invention provides a catalyst composition for inhibiting the inactivation of a catalyst for purification of compressed natural gas combustion system exhaust gas on which a noble metal component comprising platinum and palladium is supported. An oxidation catalyst, for a compressed natural gas vehicle or static combustion system exhaust gas, in which a first alumina impregnated with platinum, a second alumina impregnated with palladium, and a ceria component are supported on a ceramic support, has a barium cocatalyst supported on the first alumina, thereby greatly inhibiting inactivation of a CNG lean burn engine catalyst.

Claim (Index 1):
A catalyst for improving oxidation activity on an exhaust gas from a compressed natural gas vehicle or static combustion system in excess air, the catalyst being configured such that a platinum-impregnated first alumina, a palladium-impregnated second alumina and a ceria component are loaded on a ceramic support and the first alumina is further impregnated with a barium cocatalyst so as to improve oxidation activity on methane, which is an exhaust gas component from a compressed natural gas vehicle or static combustion system, in excess air.
