Combination of Non-Equilibrium Atmospheric Plasma and Catalyst for Gas Cleaning: NOx, VOCs, and CO Removal

Résumé

The combination of non-equilibrium atmospheric plasma and heterogeneous catalyst for automobile exhaust treatment, removal of volatile organic compounds (VOCs) from indoor air, carbon dioxide reduction, and methane reforming has attracted considerable interest in the last years. It is noteworthy that, while the catalysts are highly active and selective at high temperatures, plasma is reactive even at low temperatures albeit not selective. Instead of working independently, the combination could induce extra performance enhancement mechanisms either in a single-stage or in a two-stage configuration. Hence, the integration could generate a synergistic effect and can provide a solution for the low-temperature activation of a catalyst, which both increases the energy efficiency of the processing and improves the stability of the catalyst by reducing poisoning and coking. In this contribution, recent research activities pertaining to plasma-catalysis for environmental applications performed in GREMI Laboratory will be presented and discussed. Experiments, dedicated to that, have been conducted on various catalyst and plasma discharge systems and results will be presented with emphasis on VOCs removal from indoor air, NOx reduction as well as CO and hydrocarbons oxidation from lean-burn gasoline and diesel exhaust, and CO2 hydrogenation.
