ABSTRACT:
Metal contaminated heavy oils such as residual fractions from petroleum distillation are economically converted to gasoline and other light products in catalytic cracking by practice of a novel catalyst makeup policy of adding controlled proportions of both an active cracking catalyst and a substantially inert, large pore solid to replace the amount of catalyst withdrawn from the inventory of a continuous cracking unit wherein catalyst inventory is continuously circulated between a reactor for cracking charge hydrocarbons and a regenerator for burning off the carbonaceous deposit laid down on catalyst in the cracking reaction.
