Ionic liquids (ILs) are promising alternative solvents for traditional organic compounds using selective separation. However, some environmental risks of ILs, resulting in a limitation of their applications in industry. In this work, the stability of ILs into multi-channel tubular ceramic membranes (ILM) provides a promising way to realize the use of ILs with environmental damages reducing. This novel process has been investigated for toluene removal from a toluene/air gas mixture based on 1-butyl-3-imidazolium bis(trifluoromethylsulfonyl)amide ([Bmim][NTf₂]) as a liquid sorbent. In addition, the effects of operating conditions on toluene separation were studied and discussed by experiment and modeling. The absorption capacity of toluene by the ILM on proposed operating conditions was around 224.74 mg per gram of the ionic liquid. The support ceramic membrane can effectively prevent ILs leakage from causing secondary waste and ensuring longtime operation. Regeneration of polluted ILM was available.

离子液体（IL）是使用选择性分离技术替代传统有机化合物的有前途的溶剂。但是，IL的一些环境风险会导致其在工业中的应用受到限制。在这项工作中，IL进入多通道管状陶瓷膜（ILM）的稳定性为实现减少环境损害的IL的使用提供了一种有希望的方法。已经研究了这种新方法，用于从基于1-丁基-3-咪唑鎓双（三氟甲基磺酰基）酰胺（[Bmim] [NTf ₂]）作为液体吸附剂。此外，通过实验和建模研究和讨论了操作条件对甲苯分离的影响。在建议的操作条件下，ILM对甲苯的吸收容量约为224.74 mg / g离子液体。支撑陶瓷膜可有效防止IL泄漏引起二次废物，并确保长时间运行。污染的ILM可以再生。
