ABSTRACT:
In an ethanol fermentation process in which an aqueous solution of fermentable sugar is converted by an ethanol-producing microorganism such as a yeast to a dilute aqueous solution of ethanol with the ethanol being present in the solution at a concentration which does not exceed a predetermined maximum level, an improvement is provided which comprises selectively sorbing ethanol present in the solution within a hydrophilic crystalline aluminosilicate zeolite so that the non-sorbed ethanol present in the solution does not exceed the predetermined maximum level of concentration therein, and thereafter removing sorbed ethanol from the zeolite.
