  • Hydrocarbon cracking catalyst and process for producing light olefins
    Patent number: 10280372
    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.

  • Catalyst composition for fluid catalytic cracking, process for preparing the same and use thereof
    Patent number: 10130943
    Abstract: 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.
