This patent describes a method of fluid catalytic cracking of a hydrocarbon feed. It comprises: passing a mixture of the hydrocarbon feed and a catalyst as a suspension, through a riser conversion zone and cracking the hydrocarbon feed in the riser conversion zone; passing the mixture from the riser through a first enclosed conduit to a catalyst separator in a reactor vessel; separating catalyst from the mixture in the separator; passing gaseous effluent from the separator through a second conduit to a downstream fractionation apparatus; contacting the separated catalyst in a stripping zone with a stripping gas to strip hydrocarbons from the separated catalyst and removing stripping gas and stripped hydrocarbons, and passing the separated catalyst from the stripping zone to a regeneration vessel.
