Abstract

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.

基于MCM-22沸石的1-己烯低聚制备喷气燃料系统

轻烯烃的低聚反应是生产清洁液体燃料的一种替代方法。本研究以MCM-22分子筛为研究对象，研究了其部分无序层状结构，框架结合10元环(10 MR)对1-己烯的低聚反应。比较了MCM-22分子筛和Y分子筛的骨架结构和酸性强度对1-己烯低聚反应活性和产率的影响。结果表明，与Y型沸石相比，MCM-22型沸石是一种高效的低聚催化剂。通过核磁共振、Py-FTIR和热重分析对MCM-22分子筛进行了详细表征。研究了MCM-22分子筛在1-己烯低聚反应中的催化性能和失活性能。通过动力学研究建立了构效关系。虽然强酸位点的密度对于1-己烯的寡聚是必不可少的，低压的存在对于二聚体的形成也是必要的。因此，MCM-22沸石在1-己烯低聚反应的初始转化率和催化剂寿命方面有了实质性的改善。

期刊介绍： Carbon Resources Conversion (CRC) publishes fundamental studies and industrial developments regarding relevant technologies aiming for the clean, efficient, value-added, and low-carbon utilization of carbon-containing resources as fuel for energy and as feedstock for materials or chemicals from, for example, fossil fuels, biomass, syngas, CO2, hydrocarbons, and organic wastes via physical, thermal, chemical, biological, and other technical methods. CRC also publishes scientific and engineering studies on resource characterization and pretreatment, carbon material innovation and production, clean technologies related to carbon resource conversion and utilization, and various process-supporting technologies, including on-line or off-line measurement and monitoring, modeling, simulations focused on safe and efficient process operation and control, and process and equipment optimization.
