| The combination of pulsed positive streamer corona discharge with a platinum-rhodium catalyst was investigated for the removal of toluene, acetonitrile, and nitrogen oxides from air and synthetic air. The reactor included two parallel electrode disks made of macroscopically porous reticulated vitreous carbon. The downstream and ground disk had large internal porosity, and the surface was coated with platinum and rhodium. Contaminant removal was measured with and without plasma over a range of temperatures from ambient to 250°C, depending on contaminant light off temperature. The removal characteristics differed among the three species. The results indicate that the catalyst alone is capable of reducing nitrogen oxides and oxidizing hydrocarbons. In addition, the combination of the active catalyst with the plasma discharge was found to either enhance or interrupt catalyst activity depending on contaminant type and catalyst temperature. |
