The selective extraction of ethanol from ethanol fermentation broth through a silicalite zeolite membrane was investigated. Ethanol (98.2 wt.%) at permeate side which is above the azeotropic composition, was continuously obtained from the fermentation broth having a 20 wt.% ethanol concentration. The separation factor of ethanol over water was 218, which is higher than that from water-ethanol mixtures. This high ethanol selectivity was due to the salts that are contained in fermentation broth. The high ethanol selectivity was maintained for 48 h.
