Complete Oxidation of Harmful Organic Compounds Over Alumina Supported Cu-Mn Mixed Oxide Catalysts

Abstract

The catalytic activity of mixed alumina-supported copper-manganese oxides during complete oxidation of CO, ethylacetate, toluene and benzene is investigated. The samples were prepared by impregnation of g-Al2O3 with aqueous solutions of copper and manganese formates at room temperature and subsequent calcination at 670 K .All samples have been obtained using a fixed ratio between the two components in the impregnating solutions. The use of formates as precursors permits formation of mixed formates and their decomposition without preliminary melting thus resulting in the formations of oxide phases of high dispersity. The content of supported active metals was determined by chemical analysis. The specific surface area of the samples was measured using BET method and the magnetic susceptibility depending on temperature was investigated by the Faraday method at temperatures up to 620 K. The catalytic activity of the catalysts was measured in flow reactor.
