The reaction behavior of mixed dichloromethane (CH<sub>2</sub>Cl<sub>2</sub>) and toluene in nonthermal plasma was investigated with a ferroelectric packed-bed reactor. The decomposition efficiencies of 109 ppm CH<sub>2</sub>Cl<sub>2</sub> and 100 ppm toluene were not affected by mixing in the presence of O<sub>2</sub>. In the decomposition of(More)
The reaction behavior of dichloromethane (CH/sub 2/Cl/sub 2/)-toluene was investigated with a ferroelectric packed-bed reactor. The decomposition efficiencies of 109 ppm CH/sub 2/Cl/sub 2/ and 100 ppm toluene were not affected by mixing in the presence of O/sub 2/. In the decomposition of CH/sub 2/Cl/sub 2/-toluene, CO/sub 2/ selectivity increased with the(More)
In the removal of volatile organic compounds (VOCs) with nonthermal plasma (NTP), the additive effect of water on VOC decomposition is an important issue to be solved since water is contained in VOC exhausts. Although there have been disputed discussions on the additive effect of water on the decomposition of VOCs in NTP, a unified mechanism has not been(More)
In the decomposition of methanol, dichloromethane, toluene, and their binary mixtures with nonthermal plasma in N<sub>2</sub>, the energy efficiency for the decomposition of each volatile organic compound (VOC) increased with its initial concentration. The addition of oxygen increased the maximum energy efficiency and the corresponding reactor energy(More)
CO<sub>2</sub> reforming of methane ( CH<sub>4</sub>) and propane (C<sub>3</sub>H<sub>8</sub>) was performed with a silent discharge reactor (SDR). The reactor performance was evaluated in terms of energy efficiencies for the conversion of the substrates and formation of H<sub>2</sub> and CO. The reactivity of C<sub>3</sub>H<sub>8</sub> was 2- to 3-fold(More)
A silent discharge reactor (SDR) or a surface discharge reactor (SFR) was combined with catalysts such as MnO<sub>2</sub>, TiO<sub>2</sub>-SiO<sub>2</sub> gel, etc. to investigate the synergistic effect of nonthermal plasma (NTP) and catalysts in the decomposition of volatile organic compounds (VOCs) such as toluene (PhCH<sub>3</sub>), dichloromethane and(More)
