  • METAL-MODIFIED ZEOLITE FOR CATALYTIC CRACKING OF HEAVY OILS AND PROCESS FOR PRODUCING LIGHT OLEFINS
    Publication number: 20150165427
    Abstract: The present invention relates to a fluid catalytic cracking (FCC) catalyst containing a metal-modified ZSM-5 zeolite catalyst additive for catalytically cracking heavy oils. The metal-modified ZSM-5 zeolite may be obtained by first preparing a mixture in which the metal is introduced to the zeolite via an impregnation method or an ion exchange method, stirring and drying the mixture, and then calcining to form the final metal-modified ZSM-5 zeolite. The metal-modified ZSM-5 zeolite is used with a FCC base catalyst at different ratios to increase the production of light olefins, particularly propylene, from the catalytic cracking of heavy oils.
