ABSTRACT:
A catalytic cracking process operates with a getter additive present where hot catalyst meets heavy metals laden crude. The getter additive is a material which is selective for metals, and has a particle size/density such that the getter additive remains in the FCC unit for no more than 24 hours, and preferably is removed within one hour or less. Addition of 1-5 weight percent alumina having an average particle size of 10-40 microns will remove much of the metal content from the feed, and the metals laden additive will itself be rapidly removed from the FCC unit preventing migration of metal or degradation of the cracking operation due to the presence of metal. Preferably the additive is fine particles which are mixed with the hydrocarbon feed to the unit.
