Determination of N2O Emissions Levels in the Selective Reduction of NO_x by NH3 Over an On-Site-Used Commercial V2O5-WO3/ TiO2 Catalyst Using a Modified Gas Cell

摘要

The formation of N2O in NH3-SCR deNO_x reaction over an on-site-used commercial V2O5-WO3/TiO2 catalyst has been measured using an on-line IR system with a modified gas cell. The N2O could be formed by the SCR and NH3 oxidation reactions. These two reactions were particularly enhanced with the on-site-used sample.
