Abstract
A catalytic cracking process is disclosed in which cracking is performed in a riser reactor, catalytically cracked product is substantially separated from the catalyst in a gross-cut separator downstream of the riser reactor, and the cracked product is quenched with an anhydrous quench liquid at a location immediately downstream of the oil outlet of the gross-cut separator.
