<p><P>PROBLEM TO BE SOLVED: To provide an oxidation catalyst for burning light oil which is excellent in light oil burning performance, heat resistance, and durability and makes oxidation/combustion possible even in a low temperature region in a catalyst used to regenerate a catalyzed diesel particulate filter by forcibly burning fine particles (soot etc.) caught by the filter by high temperature gas produced by supplying light oil into the exhaust gas of an diesel engine and oxidizing/burning the light oil. <P>SOLUTION: The oxidation catalyst for burning light oil is housed with the catalyzed diesel particulate filter in a diesel engine exhaust gas pathway and arranged upstream from the filter. The catalyst is made of a heat resistant three-dimensional structure carrying catalyst components in which platinum is supported on aγ-Al<SB>2</SB>O<SB>3</SB>/La<SB>2</SB>O<SB>3</SB>mixed carrier. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
