Abstract
NO_x emitted from a stationary diesel engine generator was treated with a hybrid system comprising NO_x reduction by nonthermal plasma (NTP) and NO_x adsorption-desorption cycle. Adsorption-desorption system produces highly concentrated NO_x, which is effectively reduced by NTP treatment. Improved treatment performance and efficiency are achieved by re-injecting the NTP-treated gas mixture into the engine intake. In this study, an oxidation catalyst was employed to accelerate the system performance. It greatly enhanced the adsorption by converting NO to NO_2. The detailed analysis is reported at the presentation.
