Preparation and Gas Permeation of Zeolite 5A Hybrid PR/PVA Based Carbon Membranes

Abstract:

Hybrid carbon membranes were prepared by adopting phenolic resin (PR) and poly(vinyl alcohol) (PVA) blended polymer as precursor, and zeolite 5A as additives through pyrolysis. Thermogravimetric analysis, Fourier transform infrared spectroscopy, scanning electron microscope and gas permeation technique were used to characterize the precursor and carbon membranes. The results have shown that the thermal stability of hybrid polymeric membranes is enhanced by incorporating with 5A and defect-free hybrid carbon membranes were successfully prepared. The H2 permeability of 2125.40 Barrer and the H2/N2 selectivity of 55.9 are achieved when hybrid carbon membranes were fabricated at 700 oC.
