Abstract : Experimental and computational work conducted at the Naval Research Laboratory (NRL) to reduce NOx pollutants in a surrogate flue gas (SFG) is described. The SFG is a simulant for exhaust flue gas from a coal combustion power plant. The technology utilizes a pulsed electron beam to decompose NO and NO2. The pulsed electron beam is generated using the NRL Electra Facility. The extent of decomposition as a function of electron beam energy is studied. Fourier transform infrared spectroscopy and UV-visible spectroscopy are utilized to identify species and the extent of decomposition after the electron beam bombardment. Spectroscopic results are presented. Thermochemical calculations for possible reactions as a function of temperature are included. This report documents work completed by the NRL Chemistry Division in a collaborative effort with the NRL Plasma Physics Division.
