Abstract
Provided is a process for manufacturing a Fluid Catalytic Cracking catalyst additive composition with a novel binder. The steps involve mixing an alumina source with water to make a slurry; adding to the alumina slurry an amount of P2O5 source; the slurry is then stirred and reacted under controlled temperature and time conditions to form an aluminum phosphate binder; adding to the aluminum phosphate binder a zeolite, an amount of silica binder and an amount of clay; and spray-drying the slurry to form catalyst additive particles. The catalyst additive composition comprises a about 35 wt % to about 65 wt % zeolite; about 0 wt % to about 10 wt % silica; about 15 wt % to about 50 wt % clay and an aluminum phosphate binder comprising about 2.5 wt % to 5 wt % amorphous or pseudo-boehmite alumina and about 7 wt % to 15 wt % phosphoric acid.
