ABSTRACT:
A known method for passivating contaminant metals on an FCC catalyst comprises treating the catalyst with a sufficient amount of a sulfur-containing compound capable of associating with the contaminant metals when in contact therewith. An improvement comprises contacting the catalyst with the sulfur-containing compound for at least 3 seconds. In another embodiment of the invention, the improvement comprises contacting the catalyst with the sulfur-containing compound in a separate treatment vessel.
