Abstract
Effective quenching is provided in a catalytic cracking process to increase product yield and decrease thermal cracking. To this end, 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 an external gross cut separator before the product enters a disengaging vessel and the quench comprises cycle oil.
