“…The enhanced disappearance rate of selected organic compounds can be explained (i) by the generation of reactive oxidative species ( OH radical and hydrogen peroxide), who take part in the degradation of such compounds [10,11], (ii) by the modification of the sorbent surface [5,12], and (iii) by the electric polarization of the compounds [13,14].…”

Adsorption of pollutants on activated carbon is an effective air pollution control technique. In this study, a strong and non-uniform electric field was applied over an activated carbon fiber cloth. The adsorption kinetic of several organic compounds (Acetone, Acetaldehyde, Benzene, Cyclohexane, Ethanol, Methyl Ethyl Ketone, Toluene, 1-Propanol) on the activated carbon cloth was evaluated in the presence and in the absence of an electric field. Results suggest that its application enhances the adsorptive process. A linear correlation was found between such enhancement and the specific heat of liquefaction of the organic compounds.

“…In this process, dilute VOCs were first concentrated on an adsorbent for a long time, and then plasma-catalytically oxidized to CO 2 in a relatively short time, leading to a reduction in both energy consumption and emission of toxic compounds [14][15][16]. The adsorbent and catalyst can be separated or integrated using a dual-functional material.…”

“…Adsorption of VOCs on MIL-101 also showed shape selectivity towards VOCs molecules: The adsorption capacity of p-xylene was higher than that of m-xylene and o-xylene even though they have almost equal molecule cross-sectional areas ( Figure 5). It has also been observed that the VOC concentration can have a positive influence on the adsorption capacity of a material [22,72] and that other chemical properties of VOCs such as oxidation state can also influence adsorption.…”

“…In order to overcome these limitations, many attempts have been made and have engendered the development of a hybrid system using multiple techniques such as packed bed NTP reactors [16,17], NTP/electrostatic precipitation [18], NTP/catalysis [19,20], photocatalysis [21] and adsorption/NTP [22]. Among these VOC removal techniques, the combination of non-thermal plasma with catalysts/sorbents, i.e., plasma-catalysis, is remarkably investigated during the last decade because of their improved performance such as increased energy efficiency and suppressed unwanted This could also be an effective regeneration technique compared to conventional techniques like thermal treatment, which often leads to catalytic deactivation owing to particle agglomerations on catalyst surfaces and poses high a cost.…”

Abstract:Energy consumption is an important concern for the removal of volatile organic compounds (VOCs) from waste air with non-thermal plasma (NTP). Although the combination of NTP with heterogeneous catalysis has shown to reduce the formation of unwanted by-products and improve the energy efficiency of the process, further optimization of these hybrid systems is still necessary to evolve to a competitive air purification technology. A newly developed innovative technique, i.e., the cyclic operation of VOC adsorption and NTP-assisted regeneration has attracted growing interest of researchers due to the optimized energy consumption and cost-effectiveness. This paper reviews this new technique for the abatement of VOCs as well as for regeneration of adsorbents. In the first part, a comparison of the energy consumption between sequential and continuous treatment is given. Next, studies dealing with adsorption followed by NTP oxidation are reviewed. Particular attention is paid to the adsorption mechanisms and the regeneration of catalysts with in-plasma and post-plasma processes. Finally, the influence of critical process parameters on the adsorption and regeneration steps is summarized.
