NO REDUCTION BY SELECTIVE NONCATALYTIC REDUCTION USING AMMONIA-EFFECTS OF ADDITIVES
SINOPSIS
An experimental study of nitric oxide removal by selective noncatalytic reduction (SNCR) using ammonia as reducing agent has been performed in a semi-industrial reactor over the temperature range 973−1200 K. Several chemical compounds, such as CH4, C2H4, C2H6, CH3OH, C2H5OH, and CO, which are usually used in the literature as additives for the SNCR process, have been evaluated. As a result, very high efficiencies (up to 82%) have been achieved in our optimal experimental conditions with the classical SNCR process. The additives seem to make the NO reduction process more effective at lower temperatures. These additives induce a downward shift (up to more than 100 K) of the optimal temperature window for the reduction process, and a slight decrease of the maximum NO reduction level depending on the species and on the additive concentration. The additive utilization effectively decreases residual NH3 emissions.
