Metal-supported carbogenic molecular sieve membranes: synthesis and applications

摘要

Carbognic molecular sieve membranes supported on macroporous sintered stainless steel flat plates have been synthesized by pyrolysis of a (poly)furfuryl alcohol-acetone solution imbibed within the surface pores of the support. Permeances of H_2, He, O_2 N_2 and SF_6 were measured to determine the pemselectivity of these membranes. Experiments performed on flat-plate membranes revealed molecular sieving behavior with the permeance decreasing with increasing molecular size.
