Abstract：

Hydrophobic silicalite-1/zein composite membrane supported on a porous alumina tablet was prepared by spin coating process. Surface modification by hexamethyldisilazane and ball-milling processes could improve the dispersivity and homogeneity of silicalite-1 particles in zein ethanol solution. The homogeneous silicalite-1/zein composite membrane has an average thickness of 10μm. The pervaporation experiments show that silicalite-1/zein composite membrane can effectively concentrate ethanol from 3% and 5% ( mass fraction ) ethanol feed by pervaporation process. The total permeation fluxes and separation factors of ethanol at 303K and 313K are from 0.73 to 0.82kg.m-2.h-1 and from 4.5 to 8.7, respectively.
