Removal of volatile organic compounds (VOCs) by non-thermal plasma method: A comparison among catalysts

The oxidation and removal of dilute volatile organic compounds in a non-thermal plasma reactor with dielectric barrier discharge were examined and compared in two states with various catalysts and a plasma reactor independently. Experimental results showed the highest conversion efficiency for organic pollutants benzene, toluene, and chlorobenzene in non-thermal plasma reactors in the presence of metal oxide catalysts MnOx, AgOx, and Sintered metal fiber (SMF). In the following, a comparison between the methods of removing organic pollutants using different catalysts is made, which can be observed and compared with the effect of the type of catalyst used and the chemical composition of organic pollutants on the conversion rate.
