Effect of manganese oxide catalyst on the dielectric barrier discharge decomposition of toluene

Toluene decomposition performance and NOx by-product formation during a DBD-catalyst process

“…The selectivity of CO 2 decreased from 80.56% to 48.84% when SED increased from 140 to 320 J/L without catalyst. The result was the same as in previous reports (Guo et al, 2006(Guo et al, , 2010. But this trend was different than that reported in some papers (Magureanu et al, 2007;Karuppiah et al, 2012).…”

Plasma-induced adsorption of elemental mercury on TiO 2 supported metal oxide catalyst at low temperatures

“…The Hg 0 adsorption efficiency decreases as follows: Mn/TiO 2 N V/TiO 2 N Fe/TiO 2 N Cu/TiO 2 N Ni/ TiO 2 N Co/TiO 2 N TiO 2 . MnO x has been proposed as an effective catalyst to combine with non-thermal plasma in other investigations [40][41][42] because of its excellent redox properties at low temperatures and its interaction with active species in the plasma [43,44], which is consistent with the results in this study. In the following research, Mn was selected as the loaded metal oxide for further investigations, including for testing the effect of temperature and energy density on mercury adsorption in the plasma-catalyst system and for determining the relationship between O 2 and HCl on mercury adsorption.…”

Catalytic behavior and synergistic effect of nonthermal plasma and CuO/AC catalyst for benzene destruction

“…However, there still have some key problems need to be solved although the NTP-C has great advantages for VOCs elimination: the high cost of noble metal loaded catalysts; the synergy effect between catalytic oxidation and plasma is hard to study over laboratorial plasma reactor with small internal volume; and the removal of aromatic hydrocarbons which vast exist in industrial exhaust gases with air as the carrier gas is seldom reported. Moreover, only one or two types of catalysts were included in most of previous studies (Karuppiah et al 2014;Guo et al 2010;Zhu et al 2011;Magureanu et al 2007;Wallis, et al 2007;Zhu et al 2009). From our perspective, different metal oxides and supports have different susceptibilities to reaction parameters as energy density, water vapor, and reactant concentration.…”
