Abstract

An improved residual oil fluid catalytic cracking process for reducing catalyst deactivation caused by vanadium and/or sodium deposited on circulating catalyst used in the process from a residual oil feed, which process includes the steps of; contacting a residual oil feed in a fluid catalytic cracking reactor with hot regenerated cracking catalyst under hydrocarbon cracking conditions to convert the residual oil feed into lower molecular weight hydrocarbon product vapors and form a spent catalyst containing carbonaceous deposits including vanadium and/or sodium; separating a majority of the lower molecular weight hydrocarbon product vapors from the spent cracking catalyst to form separated product vapors and separated spent catalyst containing entrained hydrocarbon vapors; processing the separated product vapors into desired product fractions; subjecting the separated spent catalyst to stripping to remove therefrom a majority of the entrained hydrocarbon vapors; contacting the resulting stripped spent catalyst in a regenerator with an oxygen-containing regeneration gas under catalyst regeneration conditions which include a combination of a regeneration temperature and an oxygen level in the regeneration gas which is effective to burn off the spent catalyst a majority of the carbonaceous deposits, while leaving a majority of the vanadium and/or sodium on the catalyst in less than completely oxidized form, and thereby produce a regenerated catalyst having a carbon level reduced from that of the spent catalyst and containing vanadium and/or sodium, a majority of which is in less than the completely oxidized form, and; returning the regenerated catalyst to the reactor.
