The effect of temperature on the removal of DCM using non-thermal, atmospheric-pressure plasma-assisted catalysis

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-bedreactor, co-filled with TiO2 and gamma-Al2O3 catalysts. Comparisons have been made with plasma alone, catalysis alone and combined plasma/catalysis to determine any synergistic effects of combininig plasma and catalysis. Plasma/catalysis is the most successful method for destroying DCM over 125-400 degrees C. TiO2 was more effective than gamma-Al2O3 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 approximate to 30% can be achieved by plasma activation of the catalyst.
