Plasma processing of propane at Hyper-Atmospheric pressure: Experiment and modelling

A dielectric packed-bed plasma reactor was used for the destruction of propane in air and was successfully created and maintained at higher than atmospheric pressure (3 bar). The effects of pressure, REF and SED on propane removal and NOx production are discussed. An increase in SED enhances propane destruction and increases NOx production. Increasing the pressure to 3 bar produces a more efficient removal process with an energy of 877 and 600 eV per molecule at 1 and 3 bar, respectively. The pressure increase also altered the ratio of NO2 to NO2 produced from approximate to 1 to > 3, showing that substantially more NO2 than NO is produced in a 3 bar air discharge.
