Abstract: Process for the preparation of a catalyst and a catalyst comprising the use of chi or gamma or gibbsite alumina. Thus, in one embodiment, the invention provides an FCC catalyst composition comprising of ultra-stabilize Y zeolite (USY zeolite) with total Lewis acidity retention of at least above 15% when increasing the adsorption temperature from 200 to 400° C. in pyridine adsorbed FT-IR and at least above 35% retention in total acidity when increasing the desorption temperature from 300 to 400° C. in ammonia TPD measurement and at least two different alumina types wherein at least one alumina is a dispersible binding alumina sol and the other alumina is of a transitional alumina phase with XRD peaks at about 37.6 (311), 45.8 (400) and 67 (440) 2-theta (referred herein as gamma alumina) or metastable phase alumina with characteristics XRD peaks of 2? values of 37, 43, and 67 degrees (referred herein as chi alumina) or non-peptizable gibbsite-alumina has the characteristics XRD peaks of 2? values of 18, 20.

Abstract: Provided is a Fluid Catalytic Cracking catalyst additive composition and method of making the same. The catalyst additive composition comprises zeolite about 35 wt % to about 80 wt %, preferably about 40 wt % to about 70 wt %; silica about 0 wt % to about 10 wt %, preferably about 2 wt % to about 10 wt %; about 10.5 wt % to 20 wt % alumina and about 7 wt % to 20 wt % P2O5, preferably about 11 wt % to about 18 wt %, and the balance clay which can fall between 0 and 50 wt %. The alumina is typically derived from more than one source, such as at least an amorphous or small crystallite size pseudo-boehmite alumina and then either a large crystallite size alumina or other reactive alumina.

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.
