Diesel particulate filter |
摘要 |
<p>The present invention is intended to configure a diesel particulate filter to allow the burning rate of particulates to increase even with a small amount of catalytic metal or even without using any catalytic metal. In the diesel particulate filter, walls forming exhaust gas channels in a filter body on which the particulates are trapped are coated with a catalyst layer for promoting the burning of the trapped particulates. The catalyst layer contains a mixed oxide in which Ce, Zr and a rare earth element R other than Ce are contained in a Ce/(Ce+Zr) mole ratio between 10% and 90% both inclusive or between 20% exclusive and 80% inclusive.</p> |
