B01J 23/00
B01J 21/00
B01J 20/00
US Classification:
502325, 502326, 502327, 502328, 502330, 502332, 502333, 502334, 502339, 502302, 502303, 502304, 50252712, 50252713
Abstract:
The present invention provides a catalyst for use in a NOtrap that has reduced NOrelease during rich purges, increased NO conversion efficiency under stoichiometric conditions, and improved sulfur tolerance. The catalyst of this embodiment includes a precious metal, an oxygen storage component in contact with the precious metal, and a NOstorage material. The oxygen storage component in contact with the precious metal is present in an amount that provides sufficient oxygen storage capacity to reduce the NOrelease from the NOtrap during rich purges to less than 20% of the NOthat is stored in the NOtrap across the operating temperature window of the NOtrap, increase the NOconversion efficiency under stoichiometric conditions to a value greater than 70%, and increase the sulfur tolerance of the NOtrap.

Abstract:
The invention, in at least one embodiment, relates to a reverse platinum group metal zoned lean NOtrap system included in a vehicle and its method of use. One embodiment of the trap system is in a vehicle exhaust system operable during lean and rich periods. The trap system may include a first trap having a first substrate supporting a quantity of platinum and a second trap, positioned downstream of the first trap, and having a second substrate supporting a quantity of platinum and a quantity of rhodium. The total loading of platinum plus rhodium on the second trap is greater than or equal to the platinum on the first trap. In at least one embodiment, the second trap has a higher overall NOconversion at a low temperature and the first trap has a higher overall NOconversion at a high temperature.
