Resumen:
Different Fe2O3/CeO2 and Fe2O3/Al2O3 catalysts were prepared, characterized and tested for the catalytic wet peroxidation of concetrated phenol solutions (5000 ppm), at mild operation conditions. The effect of process variables, such as catalyst loading, phenol concentration or H2O2/phenol molar ratio was evaluated. The alumina-supported systems exhibited higher reaction rates and also higher final mineralization levels. The highest mineralization degrees were registered working at H2O2:phenol ratios near stoichiometric and higher catalyst mass.
