摘　　要：The oligomerization of light olefins is an alternative for generating clean liquid fuels.In this study,the MCM-22 zeolite featuring a partially disordered layered structure with framework combined 10 membered ring(10 MR)was discussed for 1-hexene oligomerization.MCM-22 and Y zeolite were compared to investigate the influences of the framework and acidity strength on the activity and yield in the 1-hexene oligomerization.The results indicated that the MCM-22 zeolite was an efficient catalyst for oligomerization compared to Y zeolite.The MCM-22 zeolite was characterized in detail by NMR,Py-FTIR,and TG analyses.The catalytic performance and deactivation properties of MCM-22 zeolite in the oligomerization reaction of 1-hexene were investigated.Structure-activity relationships were established through the kinetic study.Although the density of strong acid sites was essential for the oligomerization of 1-hexene,the presence of low pressure was also necessary for the formation of dimers.Thus,MCM-22 zeolite demonstrates a substantial improvement in initial conversion and catalyst lifespan for 1-hexene oligomerization.
