Abstract:
A method for yielding concentrated ethanol from an ethanol water solution yielded from ethanol fermentation of a water solution of saccharide generated by a saccharification of the lignocellulose by enzyme is provided. Water is separated from the ethanol water solution yielded from ethanol fermentation of the water solution of saccharide generated by the saccharification of the lignocellulose by enzyme with pervaporation method using a water separation membrane. Condensate prepared by condensing ethanol vapor existing in a space above a liquid level of the ethanol water solution is collected.
