ABSTRACT:
An integrated process is described wherein a heavy oil catalytic cracking unit is integrated with a pretreating zone. In the pretreating zone, petroleum feedstock is contacted, in the presence of hydrogen, with used equilibrium catalyst purged from the cracking zone to reduce the metals, carbon residue, and sulfur content of the petroleum feedstock prior to charging the feedstock to the cracking zone of the heavy oil catalytic cracking unit.
