This study addresses the ability of powdered transition metal oxides such as manganese oxide, iron oxide and copper oxide to catalytically oxidize low concentrations of chlorinated hydrocarbons with air. The catalytic oxidation of trichloroethylene and dichloromethane in a tubular reactor system was evaluated experimentally as a function of temperature and space velocity. Gas chromatography with electron capture detector and flame ionization detector was used for quantitative analysis of feed and product streams. Gas chromatography/mass spectrometry and gas chromatography/Fourier transform infrared spectroscopy were used to identify all oxidation products. The results indicate that over 99% conversion of trichloroethylene is achieved at 915 K over fresh iron oxide, 96% conversion of trichloroethylene is achieved at 970 K over fresh copper oxide and 74% conversion of dichloromethane is achieved at 700 K over fresh manganese oxide. The major products from the oxidation of trichloroethylene over iron oxide are CO2, Cl2 and HCl, with trace amounts of CCl4, C2Cl4 and CO.
