ABSTRACT:
A method for improving the octane rating of products from a catalytic cracking system is disclosed. The method is directed at maintaining the metal contaminant level on the cracking catalyst above about 400 wppm equivalent metal and periodically passing the cracking catalyst through a passivation zone having a reducing atmosphere maintained at an elevated temperature to passivate the metal contaminant on the cracking catalyst.
