文摘

Supported ionic liquid membranes were developed by physical infiltration of ionic liquids within porous ceramic substrates. The separation efficiency of the developed membranes regarding CO2/N2 and CO2/SO2/N2 gas mixtures was evaluated. The effect of the operation conditions on the gas permeation properties and separation performance was investigated. The nature of the counter-anion showed substantial impact on the CO2 and SO2 permeation properties. The issue of how the presence of low partial pressures of SO2 affect CO2 permeation rates was studied.
