HIGH Pd CONTENT DIESEL OXIDATION CATALYSTS WITH IMPROVED HYDROTHERMAL DURABILITY |
摘要 |
There is described Pd enriched diesel oxidation catalysts and their application as catalysts for the oxidation of CO and HC emissions from a compression ignition/diesel engine. The catalysts are characterized by increased performance and hydrothermal durability these goals being achieved by employing a layered design to eliminate low temperature catalyst quenching by toxic HC species in the exhaust stream. |
