摘　　要：采用1-己烯为原料,对硅铝比相近、不同孔结构的沸石在脉冲微反装置上进行了评价试验,考察了FCC条件下沸石孔结构对烯烃异构化性能的影响。结果表明,大孔径的Y型沸石具有良好的异构化性能,异构化能力由强到弱的排列顺序为Y>β>ZRP>丝光沸石>镁碱沸石。Zeolites with different structure and similar Si/Al ratio were evaluated on a pulse micro-reactor with 1-hexene to study the effect of pore structure of zeolites on isomerization performance of 1-hexene at catalytic cracking condition. The result suggested that Y zeolite with large pore diameter showed good isomerization performance. The rank of isomerization ability of zeolites was Y>β>ZRP> mordenite> f errierite.
