摘要: 阐述了固体酸烷基化催化剂在异丁烷/丁烯烷基化中的再生方法研究进展,包括金属临氢再生、氧化煅烧再生、超临界流体再生、洗涤再生,同时对固体酸烷基化催化剂的失活原因和失活形式进行了分析评述。这些方法在一定条件下可以实现催化剂不同程度的再生,但由于操作以及成本等原因都停留在实验室阶段,本文综合比较了各种再生方法的再生工艺过程以及再生效果,分析各种再生方法的优劣。固体酸烷基化催化剂失活较快是阻碍异丁烷/丁烯固体酸烷基化工艺工业化的关键因素,研究探索操作简单、成本低、有效的固体酸烷基化催化剂再生方法仍将是今后该领域的研究热点。

Abstract: Regeneration methods of solid acid catalyst for isobutane/butene alkylation were reviewed,including hydrogenative regeneration,classical oxidative treatment,supercritical fluid regeneration,and solvent extraction regeneration,the cause and type of deactivation about solid acid catalyst were also analyzed and reviewed. All these methods can be employed to recover the activity of solid acid catalysts in some degree,but they are all in lab research stage due to their complicate operation and high cost. This paper will compare the process and performance of these regeneration methods,analyze their advantage and shortcoming. Quick deactivation of catalyst is the key reason to hinder the industrialization of solid acid catalyst technology for isobutane/butene alkylation. Researching and finding regeneration methods,which are efficient and easily operated with low cost,will still be research focus in this field in future.

Key words: solid acid, catalyst, isobutane, butene, alkylation, deactivation, regeneration
