Abstract

Effective quenching is provided in a catalytic cracking process to decrease thermal cracking. For increased product yield, the quench is injected at special locations and a special quench is used. In the illustrated embodiment, the quench is injected into the oil product immediately downstream of a gross cut separator and the quench comprises cycle oil.
