Abstract

Poly(vinylalcohol)-tetraethoxysilane based NaA zeolite composite membranes were prepared onto the inner side of porous alumina support tube via primary crystallization processes at 100 degrees C for 4 h. Crystallization behaviour of the prepared NaA zeolite membranes was confirmed by XRD and FTIR studies. FESEM analysis revealed dense microstructure of the membrane with thickness of 15-20. m. Single gas permeation of He, N-2 and CO2 was measured with NaA zeolite membrane. Maximum permselectivity values of He/N-2 and He/CO2 were found to be 43.55 and 46.27, respectively. Pervaporation behaviour for the separation of ethanol/water mixture was studied with the membrane. Starting with 90% ethanol, 95.2% ethanol concentration was achieved within 600 min of pervaporation experiment.
