Abstract

Deep catalytic cracking of FCC(Fluid Catalytic Cracking)gasoline on LCC-2 catalyst were studied in a FCC riser reactor,using FCC gasoline as the feed.Influences of catalytic performance and process conditions on distribution and composition of the products were investigated.The experimental results showed,with the increase of reaction temperature,that the dry gas and LPG yield is increased and the gasoline yield is decreased.The LPG yield presented a maximum value at about 600℃.Aromatics and MON of FCC gasoline is increased.
