Abstract
An asymmetric membrane having a layer containing a zeolite supported on a geopolymer substrate and methods for making an asymmetric membrane having a layer containing a zeolite supported on a geopolymer substrate. A cross-flow membrane separation method for increasing the concentration of ethanol from a feed mixture comprising water and ethanol, comprising: cross-flowing a feed mixture comprising water and ethanol across the layer comprising a zeolite of the asymmetric membrane of the instant invention to produce a permeate having an ethanol concentration less than the ethanol concentration of the feed mixture and a retentate having an ethanol concentration greater than the ethanol concentration of the feed mixture, the pressure of the feed mixture being greater than the pressure of the permeate.
