Mixed matrix membranes were synthesized from poly(amide-b-ethylene oxide) (PEBAX MH1657) and zeolite 13X by a solvent casting method for CO2/N2 separation. The gas permeation properties of neat PEBAX membranes and 5, 10 and 15%(wt.) 13X loadings were determined for pure CO2 and N2 via constant volume - variable pressure method. An increase in CO2 permeability was observed with increasing loading of 13X. The greatest CO2/N2 selectivity of 47 was observed at the maximum loading. Results possibly suggest an effect on the FFV by the inclusion of the 13X.
