Performance of PES/PSF dual-layer hollow fiber membranes for H2/CH4 separation

The PES/PSF dual-layer hollow fiber membranes were fabricated by using co-extrusion method and dry-wet phase inversion technique for H2/CH4 separation. The membranes developed in this work exhibit a H2/CH4 selectivity of 64.4 and a H2 permeance of 39.9 GPU. The dual- layer hollow fiber membranes are delamination-free and no defect found in the outer skin of outer layer. The cross section morphology investigated by scanning electron microscopy (SEM) proves these results
