Influence of plasma dielectric barrier discharge on oligomerization of carbon monoxide was shown. The ratio of CO and H2 was equal to 2: 1. Gas flow-rate was 3 cm3/s for H2 and 6 sm3/s for CO. It was found that methane formation is 1.2% at parameters of dielectric barrier discharge of 0.1 J. per pulse, up to 2000 pulse per second.

The toluene being removed by dielectric barrier discharge (DBD) combined with modified photocatalyst was studied in the paper. Transition metal manganese was doped into crystal lattice of TiO2 in order to improve the activity of photocatalyst, and the optimal doping ratio was confirmed in the study. As one of main factors, the influence on toluene removal efficiency of gas flow rate, initial concentration and electric field intensity was analyzed in the study. Furthermore, the energy efficiency was another important index which had been compared amongγ-Al2O3, TiO2/γ-Al2O3 and Mn-TiO2/γ-Al2O3. The result of study showed that DBD combined with Mn-TiO2/γ-Al2O3 had the best buffer action against increasing of gas flow rate and initial concentration, the energy efficiency had the tendency as Mn-TiO2/γ-Al2O3 > TiO2/γ-Al2O3>γ-Al2O3, and the optimal doping ratio of manganese was 0.01.

A New Technique

AbstractWe propose a new technique for simultaneous decomposition of diesel particulate material (DPM) and nitric oxides (NOx) exhausted from a diesel engine. DPM and NOx are collected in a reactor using an electrostatic precipitation and a honeycomb-shaped adsorbent, respectively. After the sufficient collections, a dielectric barrier discharge (DBD) is generated in the closed space to condense and decompose DPM and NOx. DPM and NOx were decomposed simultaneously and effectively by the DBD, which act as the oxidant and reductant, respectively. It is considered that this technique is the most suitable for the decomposition of DPM and NOx with small concentration and high gas flow rate.
