CHARACTERIZATION OF THE CHEMICAL BEHAVIOR OF A DBD WIRE-CYLINDER REACTOR FOR NOx REMOVAL. DETERMINATION OF REACTIONAL PATHWAYS BY ISOTOPIC LABELING
RÉSUMÉ
The aim of this work is to determine the chemical reactivity of the DBD wire-cylinder reactor in order to control the NOx removal in a mixture of gases representing exhaust engine gases. Therefore we will qualify and quantify the major by-products of the treatment of an O2 (10%), CO2 (10%), Н2О (5.4%), С3Н6 (1000ppmv), NO (1000ppmv) and N2 (balance) mixture at atmospheric pressure and 100°C. We can observe the presence of VOC's like aldehyde (especially formaldehyde, acetaldehyde and propanal) and of R-NOx (particularly СН3-O-NO2, nitromethane and C2H5-O-NO2). We can also notice the increase of these by-products with the increase of the energy density. Finally, we demonstrate that the creation of R-NOx is due to the oxidation of С3Н6 fragments by О2 and not by CO2 contrary to acetaldehyde and propanal.
