Article Preview

Pervaporation performances of three –layer zeolite-filled poly (vinyl alcohol) composite membranes have been investigated for ethanol dehydration. Compared the neat polymer counterparts, high separation factor and high fluxes are both achieved by these membranes, indicating that ethanol/water separation is enhanced with the zeolites. Zeolites used include 3A, 4A, 5A, NaX, NaY, silicalite-1 and Beta. Through evaluating separation factor, ethanol flux and total pervaporation flux, separation performances of composite membranes are elucidated in detail in terms of the zeolite pore size, its hydrophilic/hydrophobic nature as well as its crystal framework.
