Abstract
Effects of vanadium on the structure and cracking activity of ultra-stable type Y zeolite were studied by XRD, SEM, BET, MAT and FFB. Results indicated that decreased the cracking activity by destroying the structure of SRY zeolite. Rare earth metal oxides tolerante V by reaction with vanadium components. Cerium showed more effective than lanthanum for vanadium tolerance of FCC catalysts.
