DIESEL OXIDATION CATALYST WITH LAYER STRUCTURE FOR IMPROVED HYDROCARBON CONVERSION |
摘要 |
Provided is a diesel oxidation catalyst for the treatment of exhaust gas emissions from a diesel engine and a method for treating a diesel exhaust gas stream, the method comprising providing a diesel oxidation catalyst and contacting said diesel exhaust gas stream with said diesel oxidation catalyst for the treatment of exhaust gas emissions. More particularly, the present invention is directed to a catalyst structure comprising three distinct layers; in which layer comprises a precious metal component such as palladium is located between two hydrocarbon storage layers comprising a molecular sieve such as a zeolite. |
