Extraction separation of toluene/cyclohexane with hollow fiber supported ionic liquid membrane

다국어 초록 (Multilingual Abstract)

A supported liquid membrane with ionic liquid was used for the separation of toluene/cyclohexane. Theinteractions of ionic liquid with toluene and cyclohexane were calculated and experimentally studied by quantum chemicalcalculation and liquid-liquid extraction process. The results showed [BPy][BF4] have stronger interaction with toluenethan that with cyclohexane. The selectivity of SILM processes was larger than 10 at the temperature of 323 K and theflow rate of 13.5 mL·min-1 on both shell side and lumen side. Due to the higher viscosity of IL, SILM process hadgood long-term stability. As the effects of mass transfer driving force of SILM process, the flux and removal efficiencyincreased with increase of initial toluene concentration, while the selectivity decreased because of the competitive transport.
Base on the resistance in-series model and experimental results, the mass transfer resistance was mainly lay liquidmembrane phase. The influence of flow rates on both sides was slight. The higher temperature could enhance the masstransfer performance significantly. The removal efficiency increased from 28.2% to 45.1% with the increasing of operationtemperature from 298 K to 323 K.
