Abstract

In the present study. polyethersulfone (PES) membranes on a macroporous alumina support was prepared by solvent-deposition method to separate H-2/CH4 mixture. The membrane solution viscosities were determined in order to understand the effect of PES concentration on the formation of selective membranes over a support. Supported PES membranes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and single gas permeability measurements of H-2 and CH4. The membrane casting solution with 20% PES concentration provided the formation of defecdess single-layer supported membrane. At lower concentrations. the penetration of membrane casting solution into the pores of support was prevented by using intermediate layer. hence the prepared 2-layered membrane performance was improved. H-2/CH4 ideal selectivity of best membrane exhibited is 73 at 35 degrees C. which shows promise for H-2/Hydrocarbon separation.
