ABSTRACT:
Disclosed is a method for improving fluid cracking catalyst performance by increasing metal contamination incrementally while cracking two different feedstocks that have different concentrations of metal contaminants. The relative amount of metal contamination is controlled by magnetic separation. The incrementally increased cracking catalyst is used in cracking a second feedstock.
