摘要: Abstract Permeability of gas molecules H 2 , O N and CO in four types ionic liquids ([C 4 -mim][NTf ], [C 10 [N 8881 ][NTf 8 Py][NTf ]) with a common anion but different cations supported on nanofiltration membranes was studied single feed under varying phase pressure. The separation property terms /CO selectivity the selected examined binary system also adoption liquid membrane (SILM) using (NF) as support is entirely new its operating stability investigated aiming to rectify inherent instability problem associated normal (SLMs) conventional solvents residing within microporous structure such microfiltration membranes. Gas permeation rate through SILM exhibited an exponential increase increasing pressure range from 3.0 7.0 bar, SILMs based NF were remarkably stable even at high which far exceeded for SLMs ( factor, up maximum value 4.3, variation among liquids, more interestingly, nonlinear pattern decline all reversing trend rate. Further analysis carried out attempt relate transport properties physic-chemical viscosity, polarity, cation molecular structure. good pressures relevant industrial applications opens route exploration technology enrichment, extraction separation.
