Abstract

The present invention relates to a fluid catalytic cracking additive composition for cracking of heavy hydrocarbon feed stocks and process for preparing the additive. The additive is suitable for enhancing yields of light olefins such as propylene, isobutylene, LPG and reduces the bottom yields. The invention specifically relates to a fluid catalytic cracking additive composition comprising a pentasil zeolite, zeolites having pore size in a range of 5.4-7.7 Å, alumina, colloidal silica, kaolin clay, and phosphate, wherein the zeolites having pore size in the range of 5.4-7.7 Å is present in an amount of 1 to 10 wt % with respect to the total amount of the pentasil zeolite and zeolite having the pore size in the range of 5.4-7.7 Å.
