ABSTRACT:
A zeolite-containing cracking catalyst is passivated with compounds of boron and zirconium, and preferably also antimony. The thus-passivated cracking catalyst is employed in a process for catalytically cracking a hydrocarbon-containing oil feed. In another embodiment, compounds of boron and zirconium, and preferably also antimony, are added to a hydrocarbon-containing oil feed which is catalytically cracked in the presence of a zeolite-containing cracking catalyst.
