Biobutanol is produced from fermentation by Clostridium bacteria under anaerobic conditions. Concentration of butanol in fermentation (10 g/L) is significantly lower than the concentration of ethanol in fermentation (100 g/L) because butanol is toxic to the bacteria in itself, autoinhibitor. To reduce this inhibition effect, it is necessary to separate butanol from the bioreactor immediately during fermentation process. Pervaporation is one of the best ways for butanol recovery because of its high separation efficiency, low energy consumption and harmlessness to the bacteria. We synthesized the hydrophobic zeolite, silicalite-1 and prepared PDMS/silicalite-1 composited membrane in oder to increase the butanol selectivity in the continuous pervaporation process for butanol recovery. We also investigated the effects of the operating parameters, such as feed temperature, feed concentration, membrane thickness, and silicalite-1 content on flux and separation factor.
