ABSTRACT
The objective of this work was to investigate NO, removal employing a hybrid system of a de corona discharge and a catalyst at room temperature (22°C) in the presence of ammonia. Results of the investigation showed that the hybrid system removes up to 96% of NOx with an energy efficiency of 3.4 g NO/kWh. Without the catalyst, NO, decomposition in the "pure" corona discharge with ammonia was lower (up to 66%). Also the energy efficiency was lower (about 1.8 g NO/kWh). The obtained results proved that the investigated hybrid system consisted of the corona discharge and the catalyst is attractive for NOx removal because relatively high efficiency both in decomposition and energy.

Tematem pracy było badanie procesu eliminacji NOx w układzie hybrydowym DC wyładowanie koronowe – katalizator w temperaturze pokojowej (22°C) w obecności amoniaku. Uzyskano efektywność usuwania do 96% NOx przy efektywności energetycznej 3.4 g NO/kWh. W procesie bez katalizatora stopień eliminacji NOx był niższy (do 66%), jak również efektywność energetyczna (ok. 1.8 g NO/kWh). Otrzymane rezultaty wskazują na atrakcyjność systemu hybrydowego z powodu wysokiego stopnia eliminacji NOx i wykorzystania energii.
