概要

In our previous studies, a novel NO_x aftertreatment system using adsorption and reduction by nonthermal plasma desorption is proposed. In the present study, application of the system to a real stationary diesel engine generator is investigated. The NO_x is first removed by adsorption, then the adsorbent is regenerated by thermal desorption using waste heat of the exhaust gas. In the regeneration process, hot exhaust gas passes through the heat exchanger tubes surrounded by the adsorbent pellets. The desorbed NO_x is subsequently reduced to N_2 by nitrogen nonthermal plasma. This system reduces 245〜270ppm NO_x emitted by the generator to around 50% for 8 hours.
