Abstract
Non-thermal plasma processing is an innovative technique for pollutant abatement. This approach involves the use of electrical energy for the production of free radicals which then react with the pollutant molecules. We have studied the oxidation of propene as a prototype hydrocarbon using a packed bed dielectric-barrier discharge reactor to generate the non-thermal plasma. We report the effect of three different types of material filling the reactor: glass, zirconia, and titania. The titania filled reactor shows the greatest selectivity for producing CO2 while the zirconia filled reactor has the greatest yield of total COx. In addition to COx, the plasma assisted oxidation produces small carbon containing compounds like methanol and formaldehyde.
