Abstract
A system and a method for catalytically cracking hydrocarbons. The system includes a fluidized bed riser reactor, and a separation zone configured to separate the effluent from the riser reactor to produce a product stream and a spent catalyst. A stripping zone is fluidly coupled to the outlet of the separation zone such that the spent catalyst is stripped to remove the hydrocarbons adsorbed thereon. The stripping zone encompasses at least a portion of the riser reactor such that stripping internals in the stripping zone are used to provide reaction heat to the riser reactor.
