Abstract

NOx reduction efficiency under simulated lean burn conditions is examined for a nonthermal plasma in combination with borosilicate glass, alumina, 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.
