AbstractThe aim of this paper is to give a review of the research on the decomposition of trichloroethylene (TCE), a common industrial solvent, with combined use of non-thermal plasma and heterogeneous catalysis, i.e. plasma-catalysis. This air purification technique has been investigated over the last decade in an effort to overcome the disadvantages of non-thermal plasma treatment of waste air containing volatile organic compounds (VOCs). Some examples of different plasma technologies used for plasma-catalysis are given. These include the dielectric barrier discharge, the pulsed corona discharge and the atmospheric pressure glow discharge. In a plasma-catalytic hybrid system the catalyst can either be located in the discharge region or downstream of the plasma reactor. The mechanisms that drive both configurations are briefly discussed, followed by an extended literature overview of the removal of TCE with plasma-catalysis.

Voc Abatement

Non-thermal plasma technique can be easily integrated with catalysis and adsorption for environmental applications such as volatile organic compound (VOC) abatement to overcome the shortcomings of individual techniques. This review attempts to give an overview of the literature about the application of zeolite as adsorbent and catalyst in combination with non-thermal plasma for VOC abatement in flue gas. The superior surface properties of zeolites in combination with its excellent catalytic properties obtained by metal loading make it an ideal packing material for adsorption plasma catalytic removal of VOCs. This work highlights the use of zeolites for cyclic adsorption plasma catalysis in order to reduce the energy cost to decompose per VOC molecule and to regenerate zeolites via plasma.

AbstractDilute trichloroethylene (TCE) decomposition by the non-thermal plasma processing is investigated concerning with the enhancement of the removal-energy efficiency by use of the catalyst. Tested catalysts are zeolite, titania, vanadium oxide and tungsten oxide, which are inserted into the plasma region as pellets of a few mm spheres or discs. As the zeolite adsorbs too much TCE during a long period, the enhancing effect on the removal energy efficiency by the zeolite is not yet clear, but other catalysts can surely reduce the necessary energy to decompose TCE. As there are still too many parameters affecting the removal performance, the best catalyst, as enhancing the plasma processing, and that operating conditions will be analyzed in future.

Input Energy Density

Nano-catalyst was prepared in the lab. Non-thermal plasma was generated by dielectric barrier discharge (DBD). Through nano-catalyst coupled with non-thermal plasma, a series of experiments for toluene decomposition were carried out. Based on reactor input energy density and removal efficiency and energy efficiency and inhibition for O3 formation, the load amount MnOx catalyst on the surface of γ-Al2O3 pellets were compared in the experiment. The results show the catalysis performance of 10 wt% MnOx/γ-Al2O3 coupled with non-thermal plasma resulted in higher removal efficiency of toluene and better energy efficiency. At the same time, 10 wt% MnOx/γ-Al2O3 operated on a better inhibition for O3 formation in the gas exhaust.
