An experimental NOx treatment in diesel engine combustion exhaust gases by non-thermal plasma and activated carbon filter combinations

Simultaneous removals of NOx, HC and PM from diesel exhaust emissions by dielectric barrier discharges

“…With respect to NO x abatement, Koizumi et al [13] and Herling et al [14] demonstrated that NTP processing alone has an oxidative potential to convert NO to NO 2 effectively. However, the task of NO 2 reduction would be faced with the difficulty that NTP process- ing cannot convert NO 2 into N 2 , conversely, generates a significant amount of N 2 O, HNO 3 , and/or NO 3 − [15].…”

An Experimental Study on NOx Treatment in Diesel Engine Combustion Exhaust Gases by Ozone Injection and Absorption Processes

“…This process has an effective performance for the oxidization of NO molecules to NO2 molecules. For improving the NTP chemical reaction, an effective removal process for the oxidized by-products has been required [7][8][9].…”

Discharge Plasma Assisted Adsorbents for Exhaust Treatment: A Comparative Analysis on Enhancing NOxRemoval

“…Various studies have been conducted on NO x removal from synthetic gases using hybrid plasma-adsorbent [1∼4] and plasma/catalyst reactors [5∼8] . Studies have also been conducted on actual diesel exhaust [9,10] using cascaded technique. This is important as the performance of plasma and adsorbents depend on the loading i.e.…”
