“…For positive corona, the RE decreases as the initial concentration of TCE increases. The latter observation is consistent with other studies where the effect of the initial concentration is studied [17][18][19]. It is believed that higher initial TCE concentration results in less energy available for the decomposition of each TCE molecule which causes a decrease in RE [19].…”

The decomposition of trichloroethylene (TCE) in air by non-thermal plasma was investigated with a multi-pin-to-plate direct current (DC) discharge at atmospheric pressure and room temperature. The effects of various operating parameters on the removal efficiency (RE) were examined. The experiments indicated that for low energy densities higher removal could be obtained with positive corona. For negative corona and 10% relative humidity (RH) a maximum RE of 99.5% could be achieved at 1100 J L -1 . Formation of byproducts was qualitatively analyzed in detail with FT-IR spectroscopy and mass spectrometry. Detected by-products for negative corona operated at 300 J L -1 and 10% RH include dichloroacetylchloride, trichloroacetaldehyde, phosgene, ozone, HCl, Cl 2 , CO and CO 2 . The highest RE for TCE was achieved with a relative humidity of 19%.

This paper focuses on the conversion of 1,2‐dichloroethane (EDC) using non‐thermal plasma under reaction conditions that can decompose EDC and yield a value‐added product. A cylindrical double dielectric barrier discharge system has been used to generate non‐thermal plasma and quartz has been used as a dielectric. Our findings show that under non‐oxidative reaction conditions employed in this study, vinyl chloride, a commercially important compound, is the major gas phase product produced. This paper also encompasses a preliminary characterisation of polymer during the reaction. Possible mechanisms for gaseous product formation and polymerisation are presented. magnified image

“…Non-thermal (non-equilibrium) plasma (NTP) has been more taken into account for VOCs degradation because it creates a very strong radical and oxidant agents degrading VOC molecules in ambient pressure and temperature (Magureanu et al 2007). Plasma reactors have been constructed in various designs and models.…”

Combination the non-thermal plasma technique by photocatalytic oxidation can enhance volatile organic compounds degradation. In this study, the decomposition of chloroform vapors in a novel non-thermal plasma reactor as well as an integrated system of this reactor in conjunction with the photocatalysis process was investigated. Expanded graphite was used as discharge electrode of dielectric barrier discharge reactor and the support of TiO 2 and ZnO catalysts as well. Results showed that chloroform degradation increased in hybrid system. The non-thermal plasma reactor had high content of NO and NO 2 , whereas the concentration of these two pollutants dropped dramatically in hybrid system; moreover, the generated ozone from the non-thermal plasma process was degraded on the photocatalyst and consequently was not detected in the output gas of the combined system. The generated organic by-products in non-thermal plasma process (phosgene and trichloroacetaldehyde) were reoxidized with un-oxidized chloroform in the second stage of the combined system. This increased the selectivity of CO 2 and Cl 2 .
