Preparation of multi-layer PDMS/PVDF composite membranes for ethanol recovery from water by pervaporation

摘要

The production of renewable biofuels has been received great attention due to the energy crisis and environment crisis nowadays. And ethanol biofuel is one of the most important biofuels widely used in the world. Ethanol recovery from biomass fermentation processes is inevitably due to that microorganisms used in the fermentation process usually experienced strong ethanol inhibition. Pervaporation, advantageous for the separation of azeotropic mixtures such as ethanol/water mixtures with low energy consumption, has become an efficient, cost-effective manner.
