摘要
简述了双功能催化剂上正庚烷的异构化机理,综述了负载杂多酸和金属的MCM-41、SiO2、USY、ZrO2、TUD-1、β沸石双功能催化剂上正庚烷异构化的研究进展,重点介绍了正庚烷异构化中杂多酸-金属双功能催化剂催化性能的影响因素。包括催化剂酸性、孔结构、杂多酸含量、金属含量、反应条件等。对杂多酸-金属双功能催化剂的优点和不足进行了总结,并预测了该类催化剂的发展趋势。
Mechanism of the isomerizations over bifunetional catalysts is briefly introduced, the research progress of n-hep- tane isomerizationover over heteropolyacid-metal hifunctional catalysts which are supported in MCM-41, SiO2, USY, ZrO2, TUD-1 and fl zeolite, is summarized. Influencing factors of these catalysts and their catalytic performance in n-heptane isomeri- zations are reviewed including surface acidity, pore structure, contents of heteropolyacid, metal content, and reaction condi- tion, etc. Merit and demerit of these heteropolyaeid-metal bifunetional catalysts are summarized and.development trends for these catalysts in the future are predicted.
