Methods are provided for performing fluid catalytic cracking (and/or other hydrothermal processing for cracking of hydrocarbons) on a feedstock containing hydrocarbons in the presence of a catalyst that includes zeolite Beta that is stabilized toward hydrothermal conditions. The hydrothermally stabilized zeolite Beta (including any of the various polymorphs) corresponds to zeolite Beta that is formed without the use of an organic structure directing agent, and that is further stabilized by addition of one or more stabilizers, such as lanthanide series elements or phosphorus.

The present discloses an aromatization catalyst, preparation process and application thereof and a low-carbon olefin aromatization process. The aromatization catalyst comprises a microporous material, a binder and a modifier; the microporous material is a zeolite molecular sieve, the binder is alumina, the modifier is phosphorus, and the molar ratio of the aluminum element in the binder to the phosphorus element is more than or equal to 1 and less than 5; the ratio of the acidity of the strongly acidic sites to the acidity of the weakly acidic sites of the olefin aromatization catalyst is less than 1.

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.
