Abstract
Catalytic destruction of 1,2-dichlorobenzene was carried out over two types of aerogels, vanadia-titania and manganese oxide-titania. Reactions were performed in a plug flow reactor in the range of 150–600 °C. Both catalysts resulted in very high selectivity to carbon oxides and produced negligible amount of hydrocarbon byproducts. Over the vanadia-titania catalysts, the chlorinated compound was relatively more efficiently destructed at lower temperature, while selectivity towards carbon dioxide was much higher over manganese oxide-titania aerogel catalysts. Vanadiatitania catalysts, regardless of the preparation methods, showed a tendency to produce carbon monoxide with 35–45% selectivity throughout the reaction temperature range while manganese oxide-titania exhibited more than 90% CO2 selectivity at above 400 °C.
