COMBINED SLIP CATALYST AND HYDROCARBON EXOTHERM CATALYST

COMBINED SLIP CATALYST AND HYDROCARBON EXOTHERM CATALYST

A catalyst comprising: (a) a first layer comprising an oxidizing catalyst having an effective PGM loading such that oxidation of hydrocarbons generates sufficient heat to regenerate soot, wherein said effective amount of PGM is greater than about 10 g/ft3; and (b) a second layer adjacent to said fir...
