Coozidation of Aqueous Phenol under Hydrothermal and Electrochemical Ozidation Situation with Particles of Mn-Sn-Sb/γ-Al2O3
Continual cooxidation of aqueous phenol under catalytic wet oxidation and electrochemical oxidation situation was investigated. Phenol solution was treated under conditions of reaction temperature (120-150℃), oxygen partial pressure (1.0MPa) and current intensity (0.25-1.0A) in continuous packed bed reactor with particles of Mn-Sn-Sb/γ-Al2O3. The results indicated that the presence of the electric field strongly enhanced the efficiency of the catalytic wet oxidation. Phenol conversion reached 94％ and TOC reduction was 88.4％ for an initial phenol concentration of 2500mg·L-1 at relatively mild operating conditions of 130℃ of temperature, 1MPa of oxygen partial pressure and 0.5A of current intensity. Meanwhile, the biotoxicity of effluent was three times lower than conventional catalytic wet oxidation at the same condition.
