A non-thermal, atmospheric-pressure plasma has been used to study the effect of temperature on the plasma destruction of DCM in an air stream using a BaTiO3 packed-bed reactor, co-filled with TiO2 and γ-Al2O3 catalysts. Comparisons have been made with plasma alone, catalysis alone and combined plasma/catalysis to determine any synergistic effects of combining plasma and catalysis. Plasma/catalysis is the most successful method for destroying DCM over 125-400 °C. TiO2 was more effective than γ-A12O3 for plasma/catalysis. The energy efficiency of plasma/catalysis processing compared to catalysis alone is considered by examining the input power required to achieve equivalent destructions, finding that an energy reduction of ≈30% can be achieved by plasma activation of the catalyst. © 2007 WILEY-VCH Verlag GmbH & Co.
