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

An ionic liquid process for mercury removal from natural gas.
Efficient scrubbing of mercury vapour from natural gas streams has been demonstrated both in the laboratory and on an industrial scale, using chlorocuprate(II) ionic liquids impregnated on high surface area porous solid supports, resulting in the effective removal of mercury vapour from natural gas streams. This material has been commercialised for use within the petroleum gas production indust...
متن کامل2,4-Toluene diisocyanate detection in liquid and gas environments through electrochemical oxidation in an ionic liquid.
The electrochemical oxidation of 2,4-toluene diisocyanate (2,4-TDI) in an ionic liquid (IL) has been systematically characterized to determine plausible electrochemical and chemical reaction mechanisms and to define the optimal detection methods for such a highly significant analyte. It has been found that the use of an IL as the electrolyte allows the oxidation of 2,4-TDI to occur at a less po...
