Catalytic oxidation of dichloromethane (DCM) and perchloroethylene (PCE) over different alumina supported noble metal catalysts in moist conditions was studied. Two component mixture tests with dimethylformamide (DMF), oxitol (EGEE), ethanol and ethylene were also performed. DCM and PCE were more difficult to oxidize than DMF and EGEE, the light-off temperature (T-50) of DCM and PCE was 280 degrees C and 482 degrees C, respectively. In general, the addition of V2O5 improved the activity and selectivity of the studied catalysts over the oxidation of both chlorinated VOCs. In DCM oxidation Pt catalysts were more active than Pd-containing catalysts, contrary to PCE oxidation where Pd-containing catalysts were more active. The presence of DMF enhanced the DCM conversion decreasing the T-50 value by similar to 130 degrees C. The presence of both oxitol and ethanol lowered the conversion of DCM. Removing the water feed from the inlet affected the conversion of DCM only a little but on the yield of HCl it had a major effect. In PCE oxidation the impact of additional compounds tested in this study was minor. (C) 2010 Elsevier B.V. All rights reserved.
