Improving CO2/CH4 and O2/N2 separation by using surface-modified polysulfone hollow fiber membranes
Published 2020“…Further increase in Pebax concentration from 3 to 9 wt% however negatively affected selectivities as high Pebax concentration tended to cover the membrane surface with tighter polymer chain packing which led to lower free volume. Experimental results also showed that the optimized multilayer coated membrane (3 wt.% Pebax) could achieve the highest gas pair selectivity, recording 34.28 and 6.65 for CO2/CH4 and O2/N2 separation, respectively. …”
