The present invention relates to a catalyst product for cracking of heavy hydrocarbon feed stocks predominantly into light olefins and processes for preparing the catalyst. More specifically the present invention relates to a process of preparing a Fluid Catalytic Cracking (FCC) catalyst additive composition. The FCC catalyst additive composition of the present invention is a LPG selective catalyst particles comprising a medium pore size zeolite bound by a clay-phosphate-silica-alumina binder with lowered soluble phosphate content. The catalyst of the present invention exhibits improved selectivity towards high value components like propylene and gasoline and suppressing low value components like dry gas and bottoms. The preparation comprises washing an FCC catalyst additive comprising a zeolite and phosphate with demineralised water for 30 min to 2 h to remove water soluble phosphate before drying and calcining, and subsequent ion exchange with a bivalent metal ion selected from IUPAC groups 2 and 11, filtering, drying and calcining.
