摘    要:研究了ZSM-5,Beta,MCM-22分子筛分别作为FCC催化剂添加组分的性能。结果表明,催化剂中含MCM-22的汽油和柴油产率高于含ZSM-5,与含Beta相当;气体产物的产率低于ZSM-5,高于Beta而焦炭产率比二者都高。并且发现,含MCM-22的氢转移活性比含ZSM一5和含Beta高;裂化机理比率(CMR)低于ZSM-5.与Beta相当,说明在催化裂化反应中MCM-22晶体表面的12MR孔穴起重要作用。MCM-22的催化裂化反应性能介于ZSM-5和Beta之间,更接近于Beta.

关 键 词:催化裂化  催化剂  分子筛  收率

Abstract:The performance of zeolite ZSM-5, Beta, and MCM-22 as FCC catalyst additive components was investigated. The results showed that the catalyst with MCM-22 yielded more naphtha, LCO and coke, less gas comparing with the catalyst with ZSM-5, and less naphtha and LCO, more coke and gas comparing with the catalyst with Beta. While the cracking mechanism ratio (CMR) of MCM-22 was lower than that of ZSM-5, similar to that of Beta, which meant that the 12MR cups on the crystal of MCM-22 played an important role in catalytic cracking reaction. The performance of MCM-22 in cracking reaction was between that of ZSM-5 and Beta, and was close to that of Beta.
Keywords:catalytic cracking  catalyst  molecular sieve  yield
