Abstract
Gel-coated membranes were prepared by coating hydrophobic microporous PTFE membranes with hydrophilic PVA-PAA gel and used as facilitated transport membrane for the removal of CO2 from model flue gas consisting of 10% CO2 and 90% N2. K2CO3 and Na2CO3 were used as carriers of CO2. Gas permeation experiments were performed at the permeate side pressure of 40mmHg. A facilitated transport membrane prepared by impregnating the gel layers with an aqueous 2 mol/kg K2CO3 solution showed the CO2 permeance of 2.5 × 10-5 cm3 (STP) / (cm2 s cmHg) and this value was much higher than that observed with a conventional facilitated transport membrane prepared by impregnating a hydrophilic microporous membrane with the same carrier solution. The CO2/N2 selectivity was higher than 100. It was confirmed by the long-term test that the gel-coated membrane was stable with no decrease in the CO2 permeance for continuous six-month testing period due to the hygroscopic nature of the gel layer.
