| 英文摘要 | Hydrogen is a green clean fuel and chemical feedstock. Its separation and purification from hydrogen containing mixtures is the key step in the production of hydrogen with high purity ( > 99.99%). In this work, carbon molecular sieve (CMS) membranes with ultrahigh permselectivity for hydrogen purification were fabricated by high-temperature (70 0-90 0 degrees C) pyrolysis of polymeric precursor of phenolphthalein based cardo poly(arylene ether ketone) (PEK-C). The evolution of the microstructural texture and ultramicroporous structure and gas separation performance of the CMS membrane were characterized via TG-MS, FT-IR, XRD, TEM, CO2 sorption analysis and gas permeation measurements. CMS membranes prepared at 700 degrees C exhibited amorphous turbostratic carbon structures and high H 2 permeability of 5260 Barrer with H-2/CH4, H-2/N-2 and H-2/CO selectivities of 311, 142, 75, respectively. When carbonized at 900 degrees C, the CMS membrane with ultrahigh H-2/CH4 selectivity of 1859 was derived owing to the formation of the dense and ordered carbon structure. CMS membranes with ultrahigh permselectivity exhibit an attractive application prospect in hydrogen purification.
