ADDITIVES FOR THE REDUCTION OF SULFUR IN FCC GASOLINE

摘要

Sulfur reduction ability of alumina supported zinc,gallium and zinc-gallium additives for fluid catalytic cracking catalysts was evaluated in a micro-activity test unit (MAT).Gallium/alumina showed the highest sulfur reduction of 31%,but the cracking activity of the catalyst was decreased.Zinc-gallium/alumina reduced sulfur in 24 wt.% without decreasing the base catalyst activity.
