Filled and unfilled composite GFT PDMS membranes for the recovery of butanols from dilute aqueous solutions: influence of alcohol polarity

Abstract The pervaporation performance of the silicalite-filled GFT PDMS membrane has been investigated for the separation of binary mixtures of BuOH/water and termary mixture of BuOH/acetone/water at 40°C. These components are relevant to the acetone-butanol-ethanol (ABE) fermentation process. In the range of concentrations of industrial interest ( C
