Originální abstrakt

A new type of DC atmospheric pressure glow discharge combined with thermal catalyst was applied to the removal of volatile organic compounds (VOC). Our plasma reactor closed in the discharge chamber consists of a rectangular shaped duct, in which five pins and a plate with spherical craters are positioned. The inter-electrode distance is 12,7 mm. The discharge was initiated at high voltage up to 20 kV and applied current up to 3 mA. estruction. A Cu-Mn/Al2O3 thermal catalyst (operated temperatures up to 300 celsius) is placed in series with a discharge chamber. In this study, inlet concentration range of toluene was stable at 45 ppm, no influence of the toluene admixture was observed on the thresholdcurrents. The highest removal efficiency detected was about 96 % (temperature 300 celsius; voltage 17,9 kV; current 2,5 mA). The energy efficiency of the toluene removal process and the existence of a synergistic effect of the combined application of plasma and catalysis were investigated, with the aim to operate the catalyst at a lower temperature, i.e. at a lower energy cost. We tried to explain some plasmochemical processes, such as consignable influence of generated ozone on the final VOC concentration as well.
