Mesoporous nickel silicate membranes

Catalytic membranes brought new and attractive applications of metal-incorporated mesoporous materials. Mesoporous nickel-silicate membranes were used as efficient catalysts in the selective oxidation of styrene to epoxy ethyl benzene and benzene to phenol. The use of membranes also offered a very good possibility to control the hydrogen peroxide feed and the selectivity in oxidation of styrene to styrene oxide and to increase the reaction rate. The effect of the H2O2 permeance on the conversion of styrene and benzene was also evidenced [83]. The conversion of styrene with membrane reactor has been compared with that realized in a conventional batch reactor with powdery catalyst indicating superior results. [Pg.488]
