Abstract

Official abstract text for this publication.

The present invention relates to a process for the production of ethanol using a molar excess of hydrogen. A mixed feed of acetic acid and ethyl acetate is fed to a reactor to be converted to ethanol. Hydrogen flow is increased to avoid a negative conversion of ethyl acetate.

First claim

Opening claim text (preview).

We claim: 1. A process for producing ethanol, comprising: (a) reacting acetic acid, ethyl acetate, and hydrogen in one reactor and in the presence of one catalyst under conditions effective to form a crude ethanol product comprising ethanol, acetic acid, ethyl acetate, and water; and (b) recovering ethanol from the crude ethanol product; wherein the molar ratio of hydrogen to acetic acid fed to the reactor is greater than 12:1; and wherein ethyl acetate conversion is greater…
