摘　　要：催化裂化工艺由汽油生产方案拓展到低碳烯烃生产方案,反应温度大幅度上升,导致热裂化反应更加严重,甲烷和乙烷产率显著增加。为此,将反应器出口温度高于530℃定义为超高温催化裂化反应系统,并对如何抑制该系统中的热裂化反应进行研究,提出抑制热裂化反应技术思路,由此对超高反应温度下的催化裂化反应系统进行概念设计,为降低甲烷和乙烷产率的超高反应温度下的催化裂化反应系统开发提供设计基础。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.
