%X The carbon molecule sieve membrane was prepared with coating solution of novolac phenol formaldehyde(PF) resin containing hexamine on the outer of green support from the same material.The top layer and green support were carbonized at one time.In this way,the cracks and pinholes of top layer can be eliminated effectively.The ideal selectivity of H2/CH4 and H2/N2 were 171 and 74 respectively.The obtained carbon membrane has smooth surface without pinholes judged by a scanning electron microscope.The coating solution,properties of support and soaking time have obvious effects on the properties of membrane.Molecular sieving appears to contribute to the gas permeation.
