Abstract
Cracking catalyst fines from a slurry oil are introduced into a cracking-regeneration loop not together with the highly aromatic, refractory hydrocarbon of the slurry oil but rather with a desirable hydrocarbon, such as a virgin gas oil. The invention has the advantage that the desirable catalyst fines are introduced into the cracking-regeneration loop whereas the highly aromatic oil of this slurry is not or not to a substantial extent introduced into the cracking zone.
