US 10,245,581 B2 · Composition and process for preparation of attrition resistant additive suitable for cracking hydrocarbon feed

Abstract

The present invention relates to attrition resistant hydrocarbon cracking catalyst additive composition comprising aluminum phosphate binder for cracking of hydrocarbon molecules to produce light olefins and process of preparation thereof. The present invention further relates to the process of preparation of the aluminum phosphate binder wherein said binder is incorporated into the ZSM-5 additive composition to enhance its attrition resistance property as well as enhance selectivity and activity of additive composition for production of light olefins such as liquefied petroleum gas (LPG).
