“…[Ala] was found to approach 1 mol CO 2 per mol IL, which is a factor of two greater than that reported before [94]. Similar to that suggested by Bates et al [35], Hanioka et al [90] and Myers et al [95] investigated the separation of CO 2 from gas mixtures using supported IL membranes. They synthesized a series of tetrabutylphosphonium aminoacid-based ILs and tested some of them for CO 2 uptake.…”

“…In a porous polytetrafluoroethylene (PTFE) membrane facilitated by non-functionalized ionic liquids like [C 4 Nevertheless, increase in temperature has a negative effect on the permeation of CO 2 as high temperature prevents the interaction between CO 2 and the amine moiety. The studied SILMs possess high stability, confirmed by continuous use for 260 days without detectable loss in performance [89,90].…”

A Review on Gas Separation Applications of Supported Ionic Liquid Membranes

The selection of the separation process is a critical issue in the chemical industries. Among different conventional methods for the separation processes, supported liquid membrane (SLM)-based separation processes have been predicted as a promising option. However, the industrial use of supported liquid membranes based on conventional liquids is limited by their relative instability and short lifetime. The use of ionic liquids as a liquid membrane phase results in the stabilization of the SLMs due to their negligible vapor pressure, possibility of minimizing their solubility in the surrounding phases and greater capillary force associated with their high viscosity, which can reduce the displacement of liquids from micron pores under pressure. In this review, recent advances in supported membranes based on ionic liquids including issues such as methods of synthesis IL, methods of preparation of supported ionic liquid membranes and application of supported ionic liquid membranes in gas separation are presented.

Abstract:Blend materials of Pebax ® 1657 and low molecular weight poly(ethylene glycol)s were studied for their stability at temperature up to 90°C. It was found that a threshold of molecular weight exists at which leaching out of the low molecular weight compound from the polymer matrix becomes minimal. Poly(ethylene glycol) with methyl end groups having a molecular weight of 500 g/mol provides a blend material with a CO 2 permeability coefficient higher than in case of Polyactive™. PEBAX ® /DM500 blend can be a cheaper alternative to tailor made Polyactive™ in large scale production of thin film composite membrane.

“…Hanioka et al successfully realized the facilitated transport of CO 2 and CH 4 single gases and binary mixture with N-aminopropyil-3-methylimidazolium bis(trifluoromethylsulfonyl)imide and N-aminopropyil-3-methylimidazolium triflate based SILMs. The CO 2 /CH 4 selectivity increased with the increase in CO 2 partial pressure and with the increase in temperature from 25°C to 75°C the CO 2 and CH 4 permeability increased from 500 to 1500 and from 100 to 850 Barrers respectively (Hanioka et al, 2008). Jiang and co-workers studied the permeation of N 2 , CO 2 , CH 4 and SO 2 through SILMs prepared with 1-butyl-3-methylimidazolium-, 1-ethyl-3-methylimidazolium-, 1-hexyl-3-methylimidazolium tetrafluoroborate, 1-ethyl-3-methylimidazolium triflate, 1-butyl-3-methylimidazolium hexafluorophosphate and 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide and found out that in the case of SO 2 the permeability increased, while in the other cases no significant change was observed with the increase in trans membrane pressure (Jiang et al, 2009).…”
