Abstract

Experimental study of selective non-catalytic reduction process with ammonium bicarbonate as reducing agent under various additives has been carried out and the reaction mechanism has been analyzed. Taking NO x
removal efficiency higher than 50%, with a mole ratio- of [ NH 4 HCO 3 ]/ [ NO x ] = 1 -25 as standard and under a temperature window of 860 to 980- , the NO x removal efficiency is up to 74. 63% under an optimum temperature of
935-c . U nder this optimum temperature, the NO x removal efficiencies increase with , but not significantly when -> 1 . 0. With CH 4 as the additive, the optimum temperature shifts to 880 -c and the NO x efficiency becomes lower.
With NaOH and Na 2 CO 3 as the additives, the temperature window does not change obviously and NO x removal efficiencies increase with the addition of the additives. With CH 3 COONa as the additive, the temperature window
shifts to lower a little and the NO x removal efficiencies increase also with the addition of the additives.
