The Effect of Temperature on the Removal of DCM using Non‐Thermal, Atmospheric‐Pressure Plasma‐Assisted Catalysis

Abstract

Abstract 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 BaTiO 3 packed‐bed reactor, co‐filled with TiO 2 and γ ‐Al 2 O 3 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. TiO 2 was more effective than γ ‐Al 2 O 3 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. magnified image
