Alumina supported fenton - like systems for the catalytic wet peroxide oxidation of phenol solutions / Carla di Luca in Industrial & engineering chemistry research, Vol. 51 N° 26 (Juillet 2012)

The systems were tested for the catalytic oxidation of phenol solutions (5000 ppm) with H2O2. The effects of reaction temperature, catalyst loading, phenol initial concentration, and H2O2:phenol molar ratio were evaluated. The relatively low oxidant consumption rates favored increased mineralization levels at substoichiometric H2O2 initial concentrations. The stability of the catalytic system was improved by means of a thermal treatment at 900 °C, which did not seriously affect the overall reaction performance.
