Abstract
A catalytic cracking catalyst comprising zeolite, kaolin, alumina and/or silica, antimony and 100-5,000 wt. ppm Ni is disclosed. The Ni-antimony interact in the environment of a fluidized catalytic cracking reactor to increase the magnetic susceptibility of the catalyst, permitting removal of nickel contaminated catalyst by magnetic separation.
