Abstract
Disclosed herein are processes for alcohol production by hydrogenating acetic acid to obtain a mixture of ethanol and acetic acid, esterifying the mixture to produce an esterification product and reducing the esterification product. The mixture may provide a sufficient amount of ethanol and acetic acid for esterification and reduces the need for additional acetic acid and/or ethanol. This may reduce the recycle of ethanol in the hydrogenolysis process and improve ethanol productivity.
