Abstract

original image

The cover picture shows the separation of ethanol from water using silicalite-1 membrane. The silicalite-1 membrane supported on a porous stainless-steel net has high ethanol selectivity combined with a high flux. Besides, the high mechanical stability and crack resistance of the membrane are revealed. As outlined by S. Mintova and co-workers in their Full Paper on page 437 ff., the supported silicalite-1 membrane is appropriate for ethanol extraction from aqueous bio-ethanol systems such as fermentation broths/biomass.
