Gas Separation Performance of Nano NaX Zeolite-Polyethersulfone Mixed Matrix Membranes

In this study, nano NaX zeolite-polyethersulfone (PES) mixed matrix membranes were fabricated by phaseinversion technique via solvent evaporation and the gas separation performance of the prepared membranes wereevaluated by H2 and CO2 permeation test. The influence of gas temperature and pressure on the permeability andselectivity of the membranes was also investigated. The results showed that incorporation zeolite nanoparticles into thePES membrane improved the gas separation properties as the zeolite loaded membrane had higher permeability andselectivity than the neat PES membrane. It was observed that the mixed matrix membrane has better separationperformance for H2 at lower temperature and pressure.
