The present invention relates to a novel catalyst composition for catalytic cracking of hydrocarbon streams to enhance the yield of light olefins. The catalyst composition for the cracking of hydrocarbon feed streams to light olefins, comprises a USY zeolite with silica/alumina ratio of more than 40, pentasil zeolite, a phosphate compound and alumina silica binder. The yield of olefins is further increased when the catalyst composition is impregnated with a cerium oxide. The present invention also provides a process of increasing the yield of light olefins from hydrocarbon feed streams comprising contacting the hydrocarbon streams with catalyst compositions of the present invention.

Hydrocarbon cracking catalyst and process for producing light olefins

The present invention provides a catalyst composition for use in a catalytic cracking process, said catalyst composition comprises 3.5 to 15.5% of pentasil zeolite, 9 to 40% of ultra-stable Y (USY) or rare earth exchanged USY (REUSY) zeolite, 3.5 to 15% of large pore active matrix based bottom up gradation component and 0.3 to 3% of a metal trap component, the percentage being based on weight of the catalyst composition. The present invention also provides a process for preparing the said catalyst composition and a catalytic cracking process comprising contacting the said catalyst composition with a feedstock.
