“…The power consumed by packed bed reactors for the discharge can be calculated using Lissajous curve [25] or by integrating the current and voltage waveform over one period [82,83]. In Lissajous method, the voltage applied on the high voltage electrode is measured using a high voltage probe and the dissipated charge is measured across a capacitor of capacitance , which is connected in series with the ground electrode.…”

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.

“…The thermal loss at high voltage also influences the decreases of the decomposition efficiencies. In the case of NH 3 , it appears that HNO 3 which is generated as a byproduct contributes to the NH 3 removal [ 3 ]. Although the concentration of NH 3 is decreased by the reaction, HNO 3 is generated as shown hereinafter in the reaction (13).…”

“…The plasma reactors used in this study can generate a nonthermal plasma, in which a highly chemically activated state is realized at a lower input power than that required for a thermal plasma under atmospheric pressure and temperature. The decomposition of an odorous gas using a nonthermal plasma has been reported by the authors [ 1 , 3 , 4 , 12 , 15 ]. The fundamental chemical reactions in the decomposition of NH 3 using nonthermal plasma are shown below.…”

“…Odor control has gained importance for ensuring a comfortable living environment. Previously, the authors and other researchers have reported the implementation of a nonthermal plasma odor control system in an animal house [ 1 , 2 ], odor removal from restaurants, and cigarette smoke removal [ 3 – 6 ]. A nonthermal plasma is typically referred to as an atmospheric-pressure nonequilibrium plasma, in which the gas temperature is considerably lower than the electron temperature.…”

Odor control has gained importance for ensuring a comfortable living environment. In this paper, the authors report the experimental results of a study on the detailed characteristics of a laminated film-electrode and a laminated film-electrode packed-bed nonthermal plasma reactor, which are types of dielectric barrier discharge (DBD) reactor used for odor control. These plasma reactors can be potentially used for the decomposition of volatile organic compounds (VOCs) and reduction of NOx. The reactor is driven by a low-cost 60-Hz neon transformer. Removal efficiencies under various experimental conditions are studied. The complete decomposition of the main odor component, namely, NH3, is achieved in a dry environment. The retention times are investigated for the complete removal of NH3 in the case of the film-electrode plasma reactor and the film-electrode packed-bed plasma reactor. The removal efficiency of the former reactor is lower than that of the latter reactor. Mixing another odor component such as CH3CHO in the gas stream has no significant effect on NH3 removal efficiency.
