摘要： An FCC or fluidized catalytic cracking process and apparatus for converting heavy metals laden crudes is disclosed. The heavy feed, conventional catalyst and an additive or vanadium getter contact the feed in a riser reactor. The additive is segregated from conventional FCC catalyst upstream of the conventional FCC regenerator. An elutriating, upflow riser reactor may be used with a coarse, rapidly settling getter. A fine, slowly settling getter may be used, with getter segregation achieved by using an elutriating cyclone on the riser outlet, an elutriating catalyst stripper, a sieve, or the like. The spent getter may be used once through, regenerated in a separate getter regenerator, or used as a source of fuel. Alumina and sponge coke are preferred getters.
