Abstract

The present invention relates to a composition of attrition resistant attrition resistant catalyst particularly for FCC catalyst additives such as ZSM-5, bottom cracking additive/residue upgradation additive and GSR additive comprising aluminum phosphate binder wherein said binder comprising of 1.5 to 2.9 moles equivalent of monobasic acid for each mole of mono-aluminum phosphate (MAP). Further, the aluminum phosphate binder is added to the catalyst additive to ensure effective binding of catalyst as well as preserving catalyst activity with high selectivity towards light olefins including LPG.
