Abstract

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.
