摘　　要：在中型催化裂化试验装置上,使用DCC工艺的新型催化剂MMC-2,考察反应压力对催化裂解产品分布和选择性的影响,并对反应机理进行分析。结果表明:反应压力对乙烯、丙烯和丁烯等低碳烯烃的产率和选择性均有一定影响。在一定范围内升高反应压力,DCC反应体系内的烯烃低聚反应和氢转移反应加强是影响产品分布和产品选择性的主要原因。The impact of reaction pressure on product distribution and selectivity of Deep Catalytic Cracking process are investigated on a FCC pilot plant and the reaction mechanism is discussed.The pilot test results show that the reaction pressure has an impact on the yield and selectivity of light olefins like ethylene, propylene,butylenes to some extent.The enhanced oligomerization reaction and the hydrogen transfer reaction in the DCC reaction system while the reaction pressure is elevated are the main causes af...
