Abstract: A fluid catalytic cracking unit wherein the reaction zone comprises one or more risers and a reaction vessel; wherein catalyst and oil vapors continually discharge from the risers into the reaction vessel; and wherein the reaction vessel is in communication with a stripping zone such that spent catalyst flows into the stripping zone. In operation, a selected inventory of catalyst is maintained in a fluidized state in the reaction vessel. Such selected catalyst inventory in the reactor vessel is maintained by means responsive to the pressure differential between the stripping zone and the reactor vessel. Means are also provided for controlling such pressure differential and thereby adjusting catalyst inventory in the reactor vessel.
