Investigation of CO2 separation from the CO2/CH4 gas mixture using supported ionic liquid membranes
Abstract
Some supported ionic liquid membranes (SILMs) were prepared from polyvinylidene fluoride (PVDF), polyethersulfone (PES) membranes and ionic liquids butyl methyl imidazolium tetrafl uoroborate ([BMIM][BF4]), butyl methyl imidazolium acetate ([BMIM] [CH3COO]). Prepared SILMs were used for CO2 separation from the CO2/CH4 gas mixture. The results showed that the ideal selectivity 10.72 ÷ 14.43 and the real selectivity 9.77 ÷ 12.85 of SILMs for CO2/CH4 were observed (separation yields reached 90 ÷ 93%.) The mass and selectivity of SILMs were stable after working continuously for 30 days. These results exhibit the promising potential of using SILMs for CO2 separation processes.
