This paper describes a catalytic cracking apparatus. It comprises: a cracking reactor means having an inlet for a source of hot regenerated cracking catalyst, an inlet for a source of a heavy hydrocarbonaceous feed, and an outlet for cracked products and spent catalyst comprising strippable hydrocarbons; a spent catalyst and cracked product separation means connective with the reactor outlet and adapted to separate cracked products from spent catalyst comprising strippable hydrocarbons; a spent catalyst stripping means having an inlet for spent catalyst connective with the cracked products and spent catalyst outlet of the reactor, an inlet for a stripping gas, an outlet for stripped catalyst having a reduced content of strippable hydrocarbons, and outlet for stripping gas and hydrocarbons stripped from the cracking catalyst by the stripping means.
