Abstract :
Results of the investigation of decomposition of high-concentration NO in atmospheric-pressure flowing Ar or N2 using a coaxial-line-based microwave torch plasma are presented. Concentrations of the NO in the flowing Ar or N2 were up to 2950 ppm or 4920 ppm, respectively. The highest NO decomposition efficiency was about 75% at an energy yield and specific energy density of 4.5 g/kWh and 0.4 kWh/Nm3, respectively. These values suggest the coaxial-line-based microwave torch plasma can be a useful tool for decomposition of highly-concentrated NO in Ar or N 2 at atmospheric pressure
