ABSTRACT:
A membrane catalytic reactor which comprises a heteropolyacid selected from the group consisting of 12-tungstophosphoric acid, 12-molybdophosphoric acid, 12-molybdotungstophosphoric acid, and 12-tungstosilicic acid, and polysulfone membrane is provided. This membrane catalytic reactor is applicable to vapor-phase dehydration, dehydrogenation, oxidation, and simultaneous separation of organic or inorganic materials, particularly vapor-phase dehydration of ethanol.
