Abstract:
1. A process for conversion of a liquid hydrocarbon feedstock into lower molecular weight hydrocarbon compounds in a fluidized catalytic cracking reaction and separation zone, the process comprising: a. mixing the liquid hydrocarbon feedstock and an excess of hydrogen gas in a mixing zone to dissolve a portion of the hydrogen gas in the liquid hydrocarbon feedstock to produce a hydrogen-enriched liquid hydrocarbon feedstock; b. introducing the hydrogen-enriched liquid hydrocarbon feedstock and remaining undissolved hydrogen into a flashing zone in which at least a portion of the undissolved hydrogen gas is flashed; c. passing the hydrogen-enriched liquid hydrocarbon feedstock from the flashing zone to the fluidized catalytic cracking reaction and separation zone containing fluidized solid catalytic cracking catalyst for reaction including conversion of the liquid hydrocarbon feedstock into lower boiling point hydrocarbons; and d. recovering converted hydrocarbon products from the fluidized catalytic cracking reaction and separation zone.
