Abstract

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.
