Abstract
A zeolite-containing cracking catalyst is passivated with lithium sulfate and, preferably, at least one additional passivating agent (more preferably at least one antimony compound). The thus-passivated cracking catalyst is employed in a process for catalytically cracking a hydrocarbon-containing oil feed. In another embodiment, lithium sulfate and, preferably, at least one additional passivating agent are added to a hydrocarbon-containing oil feed which is catalytically cracked in the presence of a zeolite-containing cracking catalyst.
