“…Concurrently, in recent years, to optimize the efficiency of DBD reaction chemistry, various attempts have been made to widen its applicability by introducing packing material(s) within the discharge gap (Chen et al 2006;Li et al 2010;Prieto et al 2008;Rico et al 2010;Ye et al 2008). Such packing materials were chosen to probe one or more of the following roles.…”

Assessments of ozone yield and concentration in DielectricBarrier Discharge of argon-oxygen mixtures in presence of various packing materials are discussed. These include zeolite molecular sieve 13X pellets, Pyrex beads, Pyrex wool, and porous TiO 2 -beads, which presented differential reactive surfaces, nano cavities, photo-catalysis, and dissimilar ionic environments. Their utility was evaluated in conjunction with varied gas composition, flow rate, and electrical inputs. In a mixture of 3-21% O 2 in argon, the ozone concentration ranged between 16-980 ppm, simultaneous measurements of in situ energy dissipation revealed its yield, G(O 3 ) to change independently from 0.002 to 2.020 μmol J −1 . TiO 2 packing emerged as the most versatile material to produce O 3 in high concentration and yield.

“…Alternatively, non-thermal plasma (NTP) technology is cost effective in converting diluted VOCs in large volume of air into less toxic substances [20][21][22][23]. NTP technology utilizes the supplied energy to create high energy electrons whose temperature is in the range of 10,000-250,000 K (1-25 eV) [24]; whereas the temperature of other particles remains close to room temperature [25,26]. Thus, the electrons are not in thermal equilibrium with other particles and the overall temperature of the system is maintained close to room temperature.…”

Abatement of VOCs Using Packed Bed Non-Thermal Plasma Reactors: A Review

et al. 2017

Non thermal plasma (NTP) reactors packed with non-catalytic or catalytic packing material have been widely used for the abatement of volatile organic compounds such as toluene, benzene, etc. Packed bed reactors are single stage reactors where the packing material is placed directly in the plasma discharge region. The presence of packing material can alter the physical (such as discharge characteristics, power consumption, etc.) and chemical characteristics (oxidation and destruction pathway, formation of by-products, etc.) of the reactor. Thus, packed bed reactors can overcome the disadvantages of NTP reactors for abatement of volatile organic compounds (VOCs) such as lower energy efficiency and formation of unwanted toxic by-products. This paper aims at reviewing the effect of different packing materials on the abatement of different aliphatic, aromatic and chlorinated volatile organic compounds.

A series of M–Cu (M = Mn, Ce, Cr, Co, and Fe) bimetal oxide catalysts combined with plasma were prepared for NO x removal at various temperatures. All catalysts combined with plasma exhibited excellent deNO x activity. The Mn–Cu catalyst showed the highest selective catalytic reduction (SCR) activity; the NO removal efficiency of the Mn–Cu catalyst could reach 90% at a gas temperature of 25 °C. E/N increased as gas temperature increased; the mean electron energy and the proportion of high-energy electrons also increased considerably, producing more active radicals. Without any catalyst, the increase in temperature inhibited NO removal owing to O3 consumption. As the temperature increased, NO removal efficiency decreased below 100 °C; however, it increased in the range of 100–300 °C, and then decreased above 300 °C in the plasma-catalyst system. NO2 concentration decreased markedly at 150 °C via the fast SCR reaction.
