SINOPSIS

Our goal is to develop a wire-cylinder dielectric barrier discharge reactor/or NOx removal from a gas mixture (O2:10%, CO2:10%, H2O:5%, C3H6: 1000ppmv, NO:250 to 1000ppmv, N2:balance). The NO conversion has been investigated depending on energy density and the by-products (essentially aldehydes and R-NOx) have been identified by GC-MS. Isotopic labeling of the O2 introduced helps to elucidate the reaction mechanisms leading to the formation of those by-products. For each experiment, the electrical characterization of the discharge has been carried with a digital oscilloscope, giving the measurement of the voltage, the current, the power and the electrical charge of the plasma pulses. In the second part, we simulate the NO conversion in a tubular reactor with multiple O* injections in order to qualify the role of the oxygen atoms produced by the electrical pulses.
