The present disclosure relates to an FCC catalyst additive for cracking of petroleum feedstock and a process for its preparation. The FCC catalyst additive of the present disclosure comprises at least one zeolite, at least one clay, at least one binder, phosphorous in the form of PO, and at least one Group IVB metal compound. The FCC catalyst additive of the present disclosure is hydrothermally stable and has improved matrix surface area even after various hydrothermal treatments. The FCC catalyst additive of the present disclosure can be used in combination with the conventional FCC catalyst for catalytic cracking to selectively enhance the propylene and LPG yields.

FCC catalyst additive and a process for preparation thereof

The present invention relates to a Fluid Catalytic Cracking (FCC) additive preparation process and composition, which has high efficiency in the production of light olefins C2, C3 and C4 hydrocarbons, specifically propylene. The present invention discloses the stabilization of medium pore zeolite specifically ZSM-5 using optimum phosphate salts at a pH in the range 7-9 with synergetic combination of silica rich binder to produce FCC additive having excellent stability under severe hydrothermal conditions.
