Abstract
Mordenite membranes have been prepared on the outer surface of a porous α-alumina tube by seed-assisted crystallization. The kind of silica source was found to have significant influence on the microstructure of the membrane grown on the seeded support. Highly water-selective mordenite membranes were prepared with crystallization time as short as 2-4 h at 180 °C. The dehydration of acetic acid by pervaporation was investigated using these thin membranes as functions of temperature and feed concentration. The separation mechanism is discussed.
