  • Method for promoting regeneration of a catalyst in a fluidized regenerator
    Patent number: 4222856
    Abstract: A promoter comprising from about 500 ppm to about 1% of a Group V, Group VI, or Group VIII metal on a support is combined with a hydrocarbon conversion catalyst under fluidizing conditions, in an effective proportion, to enhance the removal of carbonaceous material from the catalyst. Typically, the promoter is a mixture of platinum and palladium supported on gamma alumina and is included in a fluidized catalytic cracking (FCC) unit in a sufficient proportion to provide from about 0.05 to about 50 ppm metal based on the weight of the catalyst.
