Description Wet-air oxidation of diluted black liquor (chemical oxygen demand [COD] approximately 3250 to 14 500 mg/L) was performed at mild operating conditions (temperature 5 388 to 423 K and total pressure 5 0.6 MPa) in the presence of heterogeneous 60% copper oxide (CuO)/40% cerium oxide (CeO(2)) catalyst. Maximum COD reduction of 77.3% was obtained at 423 K at pH 3.0, which was marginally higher than that obtained at 413 K temperature (77.1%). In the acidic environment (pH
