Abstract
The catalytic wet oxidation of an azo dye was investigated at 180°C and 15 bar of oxygen partial pressure. The effects of different catalysts were examined under operating conditions selected in pre-runs of non-catalytic oxidation and thermolysis (absence of oxygen). Manganese - copper catalysts with different molar ratios were tested and MnCu5 (50% Mn and 50% Cu) was found to be the most effective, giving almost complete dye degradation and 56.8% TOC removal after 60 minutes of reaction. Moreover, this catalyst revealed to be stable regarding metal leaching and catalyst poisoning due to sulphur or carbon depositions.
