NOx Destruction in Air and Nitrogen by Dielectric Barrier Corona Discharge 982510
Destruction of NOx (200 ppm - 1%) by dielectric barrier corona discharge in zero air and nitrogen was studied at 298 K and pressure 1 atm. Effects of adding of hexane or ammonia were also evaluated. The kinetics and the products of the destruction were determined as functions of the specific discharge energy, contact time and NOx concentration. Two ranges of the specific energy deposition which reflect the competition between the destruction and production of NOx in discharge were found. At low specific energies (< 500 J/L) an efficient removal of NOx both in air and nitrogen is observed.
