摘　　要：综述了固体酸烷基化催化剂的失活原因和失活形式,总结了异丁烷/丁烯烷基化固体酸催化剂的再生方法研究进展,包含金属临氢再生、超临界流体再生、氧化煅烧再生等.对比了各类再生方法的再生效果,发现这些再生方法都可以在一定条件下将催化剂再生至不同程度,但还存在着操作条件过于严苛,成本过高等问题阻碍其工业化.因而探索操作简单、低成本且高效的再生方法将是未来研究的重点和挑战.The causes for the deactivation of various solid acid catalysts were summarized and the recent progresses made in the regeneration of these solid acid catalysts deactivated in isobutane/butene alkylation were then reviewed. The performances of various regeneration methods including metal hydrogen regeneration, supercritical fluid regeneration, oxidative treatment, etc. were comparatively evaluated. Although all these methods can recover the activity of deactivated solid acid catalysts to some degree, their industrialization was restricted by the complica-ted operation procedures, high costs and other disadvantages. As a result, the development of new regeneration methods with simple operation, low cost and high efficiency will be the focus and challenges of future research.
