Fabrication of Mixed Matrix Membrane Polysulfone-Zeolite Carbon Composites(ZCC)For Gas Separation

摘要

Mixed matrix membrane polysulfone(PSF)-zeolite carbon composite(ZCC)was successfully fabricated in this study.The composition of ZCC as a filler in this membrane was 1%.Mixed matrix membrane PSF-ZCC 1 wt% was compared by neat polysulfone membrane.The prepared membranes were characterized using XRD to determine the membrane structure and FTIR to determine the functional groups in the membrane.The results of gas permeation for membrane permeability of O2 were 4.011 and 7.193 GPU for neat PSF and PSF-ZCC 1 wt% membrane, respectively.In addition, the permeability value of N2 was 5.603 and 7.862 GPU for neat PSF and PSF-ZCC 1 wt% membrane, respectively.Selectivities of O2/N2 for neat PSF and PSF-ZCC 1 wt% membrane were 0.715 and 0.914, respectively.The increasing permeability along with the addition of ZCC filler indicated that the membrane in this study is potentially applied for O2 and N2 separation.
