摘要:

近年来研究者发现复合分子筛具有孔结构丰富、水热稳定性良好、表面性质可调控等优点,在烃类异构化反应中表现出比单一分子筛更高的反应活性和更好的异构体选择性。本文综述了丝光沸石分子筛(MOR)、Y型分子筛、β分子筛、ZSM系列分子筛、SAPO系列分子筛等两两复合的微孔-微孔复合分子筛和微孔分子筛与MCM-41分子筛、SBA-15分子筛等介孔分子筛复合的微孔-介孔复合分子筛在烷烃异构化、烯烃异构化等反应中的应用研究进展,并对用于烃类异构化复合分子筛的研究与发展方向进行了展望,指出复合分子筛用于真实石油馏分的异构化研究仍需更深入、系统地展开;采用绿色高效的合成方法合成复合分子筛以及探究通过复合分子筛的结构设计和酸性调控,如何进一步提高复合分子筛在烃类异构化反应中的活性和选择性是未来研究的重点。

Abstract:

In recent years, researchers have found that composite molecular sieves have many advantages, such as rich pore structure, good hydrothermal stability and adjustable surface properties, which show higher reactivity and better isomer selectivity than single molecular sieves in hydrocarbon isomerization. The microporous-microporous composite molecular sieves composed of MOR, Y, β, ZSM series molecular sieve, SAPO series molecular sieve and the microporous-mesoporous composite molecular sieves composed of microporous molecular sieve and MCM-41 or SBA-15 mesoporous molecular sieve were reviewed in this paper. The research and development directions of composite molecular sieves for hydroisomerization were prospected, and it is pointed out that the composite molecular sieves for real petroleum fractions isomerization still need more in-depth and systematic researches. Green and efficient synthesis of composite molecular sieves and their activity and selectivity improvement in hydroisomerization through structural design and acid regulation are the focus of future research.

Key words: isomerization, catalyst, hydrogenation, selectivity, composite molecular sieve
