The main application is in the extraction of bio-alcohols from aqueous solution. The effect of membrane composition on performance in transporting alcohols and not water at improved rates is the focus of this review. In this way the minor fraction, the bio-fuel, is removed rather than the usually large volume of water. A more economical process is then obtained. The most successful membranes are non-polar in character, and can be purely organic, inorganic or organic-inorganic polymer hybrids. For ethanol recovery, flux rates are best for polydimethylsiloxane (PDMS) when used as a very thin layer on a supporting base. Zeolites give the best separation factors along with reasonable fluxes, and supported silicalite performs well. For butanol recovery, flux rates are best for PDMS mixed matrix membranes. A styrene copolymer membrane gives a reasonable result for benzene/cyclohexane separation, while metal-organic frameworks have potential in the separation of organic isomers, where pore geometry becomes important.}, keywords = {Organophilic pervaporation,Organic polymer membranes,Inorganic membranes,Mixed matrix membranes,Metal-organic frameworks,Biofuels}, url = {https://www.msrjournal.com/article_24625.html}, eprint = {https://www.msrjournal.com/article_24625_03bec751dc44655396c034331efab952.pdf} }
