Original Abstract

The problem of VOCs is one of the urgent tasks in contemporary research. Besides the classical techniques, the plasma assisted combustion methods are widely developed. The contemporary experiment was focused on the VOC decomposition in planar surface dielectric barrier discharges using alumina ceramics. The photocatalytic TiO2 was prepared by various techniques based on ink-jet printing on inner side of discharge ceramic plates. The exhaust gas analyzis was carried out by simple gas analyzer Testo 350-XL that was used for the detection of simple low molecular weight discharge products as CO, NO2, NO, H2, etc. The analyzes of discharge exhaust gas showed the high concentration of CO in decomposition of xylene. For measurements, the different layers of TiO2 photocatyzer were used. The higher concentrations of all low weight discharge products was observed then smoother layer was used and a strong frequency dependence of its efficiency was observed if cyclohexane was used.
