Combination of non-thermal plasma and Pd/LaMnO3 for dilute trichloroethylene abatement

Non thermal plasma assisted catalysis of methanol oxidation on Mn, Ce and Cu oxides supported on γ-Al2O3

“…It was also demonstrated that the presence of a catalyst within a plasma discharge resulted in a synergistic effect and was improving VOCs and by-products conversion. Various publications and reviews give detailed reports on non thermal plasma (NTP) coupled to catalysis on VOCs removal such as trichloroethylene [8,[11][12][13], benzene [8,[14][15][16], toluene [8,17,18], isopropanol [19][20][21] and methanol [22][23][24][25]. In particular, a significant attention has been brought on manganese oxide based catalysts, owing to their capacities to store oxygen and activate ozone [11,16,17,19,[25][26].…”

“…However, they generate ozone and NO x , which must be eliminated and so requires post‐treatment by filtration and/or catalytic decomposition of the exhausts . For good efficiency, such system should be placed downstream of the plasma discharge (post‐plasma catalytic or PPC system) as illustrated in the case of trichloroethylene abatement on Pd/LaMnO 3 or of methanol oxidation on Mn, Ce, and Cu oxides supported on γ‐Al 2 O 3 . The synergetic association of the plasma technology with a photocatalytic pathway is also of particular interest, as proposed in recent studies on ethanol abatement in air on MnO x /TiO 2 catalysts or on the elimination, on a TiO 2 supported on glass fiber material, of isovaleraldehyde, a molecule present in the exhaust gases from animal quartering centers …”

Ethylene epoxidation in a low-temperature parallel plate dielectric barrier discharge system with two frosted glass plates

“…The studied DBD was operated under oxygen lean conditions in order to minimize all undesirable reactions including partial and complete oxidation (Eqs. (8)- (17)) and cracking reactions (Eqs. (24)- (27)).…”

“…Therefore, a search for a new method with lower energy consumption, a lower reaction temperature and without the use of a catalyst is of great interest. Non-thermal plasma has been reported to be an alternative technique for several reactions including ethylene epoxidation [7,8], natural gas reforming (H 2 production) [9][10][11][12][13], chemical vapor deposition [14][15][16][17][18][19][20][21], and desulfurization [22,23].…”
