Abstract
A high-performance organosilica membrane was prepared via sol-gel processing for use in methylcyclohexane (MCH) dehydrogenation to produce high-purity hydrogen. The membrane showed a high H2 permeance of 1.29 Ã 10â6 mol mâ2 sâ1 Paâ1, with extremely high H2/C3H8 and H2/SF6 selectivities of 6680 and 48,900, respectively, at 200 °C. The extraction of hydrogen from the membrane reactor led to the MCH conversion higher than the thermodynamic equilibrium, with almost pure hydrogen obtained in the permeate stream without considering the effect of carrier gas and sweep gas in the membrane reactor, and the organosilica membrane reactor was very stable under the reaction conditions employed.
