焦化苯中噻吩脱除与回收的研究进展

Research Progress on the Recovery and Removal of Thiophene in Coking Benzene

综述了萃取精馏、冷冻结晶、吸附分离和离子液体四种脱除并回收焦化苯中噻吩的方法,对它们的优缺点进行了比较与评述,认为选择性吸附是回收焦化苯中噻吩最具工业化应用前景的方法,但高效吸附剂的研究与开发是关键。

The extractive distillation,freeze crystallization,adsorption separation and the ionic liquid method,which can be used to remove and recover the thiophene in coking benzene,were reviewed.The advantages and disadvantages were compared and described.The selective adsorption was considered to be the most promising method of industrialization to remove and recover the thiophene,but research and development of highly efficient adsorbents was the key.
