“…In the case of gliding arc discharge, the concentration of NO 2 reaches up to several thousand ppm [20]. Kuroki et al reported NOx formation problem from the decomposition of adsorbed xylene on zeolite using AC barrier discharge plasma in air [24]. Microwave (MW) plasma is also known to produce high concentration of NO and NO 2 (∼4000 ppm) when it is operated at air-like mixture [25].…”

Abstract. Combination of two old-yet-new technologies (plasma and catalyst) is getting attentions for the advanced processes in 21 century. This paper reports the complementary combination of atmospheric pressure nonthermal plasma with catalyst for the air pollution control application. The most important feature of this complementary combination is that plasma enables catalyst to work even at room temperature. Up-to-date data on catalyst screening for the cycled system will be given in terms of enhancement factor and adsorption capacity. Visual observation using ICCD camera was applied to study how discharge plasma interacts with catalyst at atmospheric-pressure and ambient temperature.

“…However, the authors reported that the conversion rate of toluene to COx and the energy efficiency of the toluene to COx conversion were increased with the amount of adsorbed toluene. By the same research group, a xylene decomposition system was also investigated using different NTP plasma sources (60-Hz neon transformer and inverter-type neon transformer) with gas circulation [60]. Inverter-type neon transformer showed better performance (higher conversion ratio of xylene to COx and higher energy efficiency) than the 60-Hz neon transformer.…”

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.

“…It is also used to sterilize many substances (Grodowska andParczewski 2010, Kartheek et al 2011). Also, according to Kuroki et al (2010), xylene is used as solvent and fixative. Chemical fixatives are used to preserve tissue from degradation and to maintain the structure of the cell and the subcellular components such as cell organelles (e.g., nucleus, endoplasmic reticulum, and mitochondria).…”

Addressing environmental degradation and ensuring environmental sustainability are inextricably linked to all methods of reducing volatile organic compounds (VOCs) from the environment. A packed column air stripper is a typical example of such technologies for the removal of VOCs from polluted water. The present review is devoted to the applications of a packed column air stripper and, in comparison with previous reviews, presents further elaborations and new information on topics such as modeling and simulation of the dynamic behavior of the air stripping process in a packed column air stripper. The paper observed that a knowledge gap still exists in the synthesis of this knowledge to formulate practically applicable mathematical relationships to describe the process generally. Therefore, further researches are still required in the area of air stripper performance optimization, particularly in the development of a mathematical model and the optimization of an air stripper using a statistical experimental design method. Such a determination is critical to the understanding of the interactive effect of process variables such as temperature, air-to-water (A/W) ratio, and height of packing on air stripper performance.
