- NOx reduction efficiency under simulated lean burn conditions is examined for a non-thermal plasma in combination with borosilicate glass, alumina, titania, Cu-ZSM-5 and Na-ZSM-5. The non-thermal plasma alone or with a packed bed of borosilicate glass beads converts NO to NO2 and partially oxidizes hydrocarbons. Alumina and Na-ZSM-5 reduce a maximum of 40% and 50% of NOx respectively; however, the energy cost is high for Na- ZSM-5. Cu-ZSM-5 converts less than 20% with a very high energy consumption. The anatase form of titania reduces up to 35% of NOx at a relatively high energy consumption (150J/L) when the catalyst is contained in the plasma region, but does not show any appreciable conversion when placed downstream from the reactor. This phenomenon is explained by photo-activation of anatase in the plasma.
