Abstract:
It was shown that acetic acid can be obtained from aqueous ethanol (6–40 mol%) solutions over Cu/ZnO–ZrO₂–Al₂O₃ catalyst at 250–320^◦C and atmospheric pressure. Selectivity of 80–90% and spacetime yield of acetic acid up to 9 mmol gcat−1 h−1 at 60–80% ethanol conversion were obtained while processing 14–37 mol% aqueous ethanol solutions. Hydrogen was generated in an amount ∼2 moles per 1 mole of acetic acid as a co-product.

Keywords:
Ethanol
Acetic acid
Cu-containing catalyst
