简介：Inthispaper,AgBF4/[emim][BF4]supportedionicliquidmembranes(SILMs)werepreparedsuccessfullyforCO/N2separationusingnitrogenpressureimmobilizationprocedures.TheincorporationofAgBF4coulddecreasemembraneweightloss,improvethepressure-resistantability,andkeepthecriticalpressure(0.45MPa)oftheSILMs.ThehighviscosityandundissolvedAgBF4solidsinmembraneliquidwoulddisturbgasmoleculartransportthroughmembraneandgiverisetothegastransportresistance.Therefore,thegaspermeabilitydecreasedremarkablywithincreasingAgBF4carriercontentinthemembrane.WhenthemolarratioofAgBF4to[emim][BF4]increasedfrom0:1to0.3:1,theCO/N2selectivityoftheSILMsshowedagreatincreasefrom~1to~9at20°Cand0.4MPa,suggestingthatAgBF4wasaneffectivecarrierforCOfacilitatedtransport.ThepermeabilitiesofN2andCOincreasedathighertransmembranepressure,indicatingthatmoleculartransportwoulddominatethetransportprocessathighpressure.Thetemperature-dependentgaspermeabilityfollowedtheArrheniusequation.Moreover,thedifferencesbetweentheactivationenergiesofCOandN2becamelargerafterintroducingAgBF4,resultinginmoreobviousdecreaseintheCO/N2selectivityathigheroperatingtemperature.
