ABSTRACT:
A process for catalytically cracking a hydrocarbon-containing feed stream, preferably having an API.sup.60 gravity of about 5-30, wherein at least a portion of off-gases is treated so as to remove C.sub.2 -C.sub.4 olefins therefrom, and the off-gas stream having a reduced olefin content is then recycled to the catalytic cracking zone.
