ABSTRACT:
Ethanol is recovered from a fermentation mixture by contact with a crystalline zeolite sorbent exemplified by ZSM-5, followed by desorption of concentrated ethanol. In one embodiment of this invention, the sorption step is conducted during fermentation to maintain the ethanol concentration in the fermenting mixture at a concentration below that which is toxic to the fermenting organism.
