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