  • Catalytic cracking using a cracking catalyst in admixture with particles of platinum group metal or rhenium on a substrate regenerated to up to about 0.1% coke
    Patent number: 4435282
    Abstract: An improved fluid catalytic cracking process comprises a method for the regeneration of the fluidizable hydrocarbon conversion catalyst, particularly of the molecular sieve type, which has been deactivated with coke deposits while employed in a hydrocarbon catalytic cracking process, in which the coke-containing hydrocarbon conversion catalyst is contacted with an oxygen-containing gas to burn the coke from the catalyst under conditions providing substantially complete combustion of carbon monoxide and substantially complete combustion of the coke on the catalyst. In the regenerator, particles of the hydrocarbon conversion catalyst are in association with particles of a platinum group metal or rhenium oxidation catalyst which promotes the combustion of carbon monoxide to carbon dioxide. The catalyst composite contains a mixture of cracking catalyst particles and particles having the platinum group metal or rhenium oxidation catalyst supported on a substrate.
    Type: Grant
    Filed: April 19, 1982
    Date of Patent: March 6, 1984
    Assignee: Standard Oil Company, (Indiana)
    Inventors: Ralph J. Bertolacini, William L. Forsythe, Jr.
