摘要:
The oxidation of carbon monoxide (CO) and hydrocarbons (HC) in an oxygen-containing gas stream, such as the exhaust stream from a diesel engine, or other lean-burn engine, may be catalyzed using a combination of mixed oxide particles of cerium, zirconium and copper, and discrete particles of an alumina-supported platinum group metal catalyst. The catalyzed oxidation of CO and HC by this combination of oxidation catalyst particles is effective at temperatures below 300° C.
