| 摘 要： | 概述分子筛的酸性特点,介绍固体酸催化的异丁烷/丁烯烷基化反应机理,并对已用于异丁烷/丁烯烷基化反应的分子筛情况进行总结,重点阐述分子筛的酸性对烷基化反应性能的影响。结果表明,分子筛应有合适的酸强度,综合来看,中强B酸更有利于反应。今后的机理研究中应当关注L酸及酸位空间分布对烷基化反应的影响。

| Abstract: | This paper discusses the acidic properties of zeolites,the mechanism of isobutane/butene alkylation catalyzed by solid acid,the zeolites active for the aforementioned reaction,and the effect of acidic properties of zeolites on the performance of alkylation.Previous studies show that the acid strength of zeolites should be in a suitable range,and generally Brønsted acid sites with middle-strong strength is more conductive to the reaction.We should pay more attention on the effect of Lewis acid sites as well in the future. |
