ABSTRACT:
An improved method for passivating metals in a hydrocarbon feedstock during catalytic cracking has been discovered. The method involves contacting the feedstock with a passivating agent comprising a precipitated porous rare earth oxide, alumina, and aluminum phosphate precipitate. The passivating agent may be coated on a cracking catalyst, be part of the matrix of a cracking catalyst, or be added to the cracking operation as discrete particles.
