摘要： The processes of the current invention relate to the production of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid and ethyl acetate. Conversion of ethyl acetate may be improved by controlling the water content that may be fed to the vaporizer to form a feed stream that may be fed to the hydrogenation reactor. At least 0.01 wt. % water is fed to the vaporizer. The crude ethanol product is separated two or more columns to yield an ethanol product.
