Ethanol production processes using a mixed feed comprising from 20 to 95 wt. % acetic acid, from 5 to 80 wt. % acetic anhydride, and from 0 to 20 wt. % esters selected from the group consisting of methyl acetate, ethyl acetate, or mixtures thereof are disclosed herein. The process comprises contacting the mixed feed with hydrogen in the vapor phase in a reactor in the presence of a catalyst comprising tin, cobalt, platinum, and combinations thereof to form a crude ethanol product having an ethanol to water molar ratio of greater than 1 and separating the crude ethanol product in one or more distillation columns to yield an ethyl acetate stream and an ethanol stream. The process may be integrated with an acetic anhydride production process to obtain further economic savings.
