ABSTRACT:
Combustible carbonaceous particles such as particles of sponge coke or coal are incorporated with the circulating inventory of cracking catalyst in a fluid catalytic cracking unit. The carbonaceous particles selectively sorb metal contaminants in the feed, thereby extending catalyst life, and they also serve to reduce NO.sub.x emissions in certain instances. The sorbed metals values may be recovered as the carbonaceous particles are burned.
