AROMATIC VOC REMOVAL BY MICROPARTICLES FORMATION IN PURE NITROGEN
ABSTRACT
The reactivity of toluene in a DBD discharge was studied for two different mixtures: 400 ppm of toluene diluted in synthetic air (80% N2 + 20% O2) or in pure N2. The reactivity was compared in terms of pollutant conversion and by-products formation. Regarding the pollutant conversion, the destruction efficiency was comparable with or without oxygen. However, the decomposition of toluene in pure N2 leads to the formation of micrometric particles. These particles could be easily removed by filtration. On the contrary, in the case of a DBD treatment in air, 50% of the destroyed pollutant was oxidized in CO and CO2. The other products that could be detected were ring retaining (nitroaromatics) or non ring-retaining products. In both case, the analyses of the species produced in gas-phase using GC-MS technique allows the determination of the reaction pathways.
