Abstract:
A process for purifying ethanol by using a finishing reactor to remove impurities, such as ethyl acetate, acetaldehyde, acetic acid, and diethyl acetal, present in ethanol after distilling a crude product from a hydrogenation reactor. The finishing reactor may reduce the impurities in the presence of hydrogen and a catalyst or may hydrolyze the impurities.
