Abstract

The present invention relates to a process for the formation of ethanol from a mixed feed, the steps of the process comprising: contacting a feed stream containing the mixed feed and hydrogen at an elevated temperature with a hydrogenation catalyst comprising from 3 to 25 wt. % of a substantially equal molar ratio of cobalt and tin on a support, wherein the mixed feed comprises 5 to 40 wt. % ethyl acetate and 60 to 95 wt. % acetic acid.
