Abstract

A fluidized catalytic cracking apparatus for catalytically cracking a heavy hydrocarbon feed to lighter products includes a regenerator shell for heating spent catalyst, the regenerator shell having a bottom riser for introduction of the heavy hydrocarbon feed, a catalyst, and steam, and from which flows a stream, the bottom riser having a distributor for allowing the stream from the bottom riser to be distributed into a plurality of reaction tubes positioned within the regenerator shell; a catalyst separator connected to an upper end of the regenerator shell; a stripper connected to the catalyst separator to cause a stripping of the catalyst and the spent catalyst feed to the regenerator shell; and an air inlet provided in the regenerator shell so as to cause a combustion within the regenerator shell.
