RESEARCH AND CONCEPTUAL DESIGN OF FLUID CATALYTIC CRACKING REACTION SYSTEM AT ULTRA-HIGH REACTION TEMPERATURE
The fluid catalytic cracking process has been developed from gasoline production scheme to light olefin production scheme,and the reaction temperature has increased significantly,which has led to more serious thermal cracking reaction,and the methane and ethane yield increases significantly.Therefore,the reaction taking place in the reactor with outlet temperature higher than 530℃ is defined as the ultra-high temperature fluid catalytic cracking reaction system,and how to inhibit thermal cracking reaction in this system is studied,and the technical idea of inhibiting the thermal cracking reaction is proposed.The conceptual design of the ultra-high temperature fluid catalytic cracking reaction system can provide a design basis for the development of the fluid catalytic cracking reaction system at ultra-high reaction temperature to reduce the yield of methane and ethane.
