Abstract A FCC catalyst for decreasing the olefin content in gasoline is prepared from zeolite-type active component, amorphous silicon aluminium oxide and kaolin through mixing composite molecular sieve, oxide adhesive and kaolin, spraying, solidifying, washing and drying. Said active component contains ZSM-5, rare-earth Y-zeolite, phosphorus and compoiste rare-earth modified utlra-stable Y-zeolite. Its is high effect while not changing the octane value.
