It was shown that acetic acid can be obtained from aqueous ethanol (6–40mol%) solutions over Cu/ZnO–ZrO 2 –Al 2 O 3 catalyst at 250–320°C and atmospheric pressure. Selectivity of 80–90% and space-time yield of acetic acid up to 9mmolg cat−1 h −1 at 60–80% ethanol conversion were obtained while processing 14–37mol% aqueous ethanol solutions. Hydrogen was...
