摘要

加氢异构反应在提升汽油辛烷值、柴油降凝和润滑油基础油脱蜡降黏等方面应用广泛。一维孔沸石对直链烷烃具有独特的孔口择形效应，是加氢异构反应中最适宜的酸性载体和异构化活性组分，其异构化性能主要取决于沸石拓扑结构、酸性质、晶粒尺寸等自身因素。主要概括了近年来不同拓扑结构一维孔沸石的合成、改性及应用的研究进展，讨论了常用于加氢异构的一维孔沸石分子筛的发展趋势，并对其应用前景进行了展望。

Abstract

Hydroisomerization reactions are widely adopted in octane upgrading,diesel fuel coagulation reduction and lubricant base oil dewaxing and viscosity reduction.One?dimensional pore zeolites have unique pore?selective effects on straight?chain alkanes,and thus server as the most suitable acidic carrier and active component for isomerization in hydroisomerization reactions. Its isomerization performance is mainly depended on the topologic structure,acid properties and crystal size of zeolite.This paper mainly summarizes the research progress of synthesis,modification and application of one?dimensional pore zeolites with different topologies in recent years as well as the development trend and application prospect of these zeolites for hydroisomerization.
