ABSTRACT:
A fluidized catalytic cracking process wherein the reaction zone comprises one or more riser reaction conduits discharging into a reaction vessel. Hydrocarbon vapors and catalyst discharging from the risers separate to form a dense phase fluidized catalyst bed and a hydrocarbon vapor phase within the reaction vessel. A selected weight inventory of catalyst is maintained in the reaction vessel dense phase catalyst bed by valve means responsive to the weight of catalyst. Conversion of hydrocarbon in the reaction vessel may be increased by reducing the dense phase catalyst bed bulk density and consequently increasing contact of catalyst with hydrocarbon vapor within the reaction vessel.
