ABSTRACT:
Metal-contaminated oils, including mildly hydrotreated residual oils, are catalytically cracked in the absence of added hydrogen in a fluid catalytic cracking process wherein the regenerated catalyst has less than about 0.05 wt. % residual carbon. By conducting regeneration of the catalyst to that level at 1300.degree. to 1400.degree. F. (preferably at about 1350.degree. F.) with excess air, additional benefits are realized in that metal deposited on the catalyst by cracking of residual stocks is thereby passivated.
