The experimental system of NO conversion in N2/NO mixtures by non-thermal plasma (NTP) based on spectroscopy diagnosis was established. The NO chemical mechanism was analyzed by combining with emission spectroscopy diagnosis of dielectric barrier discharge (DBD). The impact of NTP system operating parameters and N2 volume flow rate on NO conversion rate was also studied. The ratio between N2 emission...
An active catalyst of Ag/γ-Al2O3 was prepared by impregnation method. The main components of the catalyst were characterized by X-ray diffraction (XRD). A non-thermal plasma (NTP) reactor was designed based upon dielectric barrier discharge and the non-thermal plasma assisted catalyst (NPAC) system was established. The bench test was carried out and the reduction of diesel engine harmful emissions...
Inverter power of series resonant type are commonly used in dielectric barrier discharge, By means of theoretical analysis and experiments based on Q-V Lissajous figures, study on optimal matching of DBD load and inverter power are carried out to improve the working performance and efficiency of DBD device. The result indicate that: as the DBD equipment's discharge power enhanced, the dielectric equivalent...
Through establishing dielectric barrier discharge (DBD) experiment system, the effects of applied voltage (V) and its frequency (J) on the main parameters of DBD were studied by Q-V Lissajous figures method, some conclusions could be drawn that improving V and f effectively enhanced DBD power(P) and charge transfer value(Q); when DBD device structure parameters were certain, the effects of V and f...
