摘要：A series of MnxCey/Al2O3 mixed oxides catalysts with different compositions prepared by wet impregnation method were tested for catalytic combustion of chlorobenzene (CB), as a model of volatile organic compounds of chlorinated aromatics. MnxCey/Al2O3 mixed oxides catalysts present high activity for the low temperature catalytic destruction of CB and Mn8Ce2/Al2O3 catalyst is identified as the most active catalyst, on which the temperature of complete combustion of CB is 338 degrees C. Effects of systematic variation of reaction conditions, including space velocity and inlet CB and oxygen concentration on the reaction were investigated. Additionally, the stability and deactivation of MnxCey/Al2O3 mixed oxides catalysts were studied by various characterization methods and other assistant experiments. MnxCey/Al2O3 mixed oxides catalysts with high Mn/Ce ratios present a stable high activity, which is related to their better reducibility. (C) 2010 Elsevier B.V. All rights reserved.
