摘要
综述了轻质烷烃异构化催化剂的研究现状及发展趋势,总结了轻质烷烃异构化反应的特点,介绍了有代表性的氯化铝型、分子筛型、固体超强酸型轻质烷烃异构化工业催化剂,并分别从反应温度、产品辛烷值、抗毒性等方面对比了几种工业催化剂的性能及优缺点。重点从活性组分和载体两方面描述了各类轻质烷烃异构化催化剂的最新研究进展,包括Pt/zeolite、Pt/Zr O2-SO4、杂多酸、Pt/WO3-Zr O2、介孔材料、钼基催化剂、离子液体等,同时提出了催化剂研究中面临的一些问题。最后指出了低温、高抗毒性的轻质烷烃异构化催化剂将是未来研究的焦点。
The research status and development trend of light paraffin isomerization is reviewed. Characteristics of the light paraffin isomerization process are summarized. Some commercial catalysts are introduced,and the performance parameters of reaction temperature,RON,antitoxicity are compared. Based on components and support,the development of light paraffin isomerization catalysts is reviewed with respect to Pt/zeolite,Pt/ZrO2-SO4,heteropoly acids,Pt/WO3-ZrO2,mesoporous materials,Molybdenum based catalysts,ionic liquids,and some problems in the study of catalysts are indicated. In the future,lower reaction temperature and antitoxicity catalyst will be paid increasing attention.
