EXPERMENTAL STUDY ON SEQUENCE HEATING REACTION BETWEEN NITRIC OXIDE AMMONIA

A tubular reactor with a sequence heating device is used to discuss the effects of operational parameters fo r the reaction between nitric oxide and ammonia. Experimental results showed that denitration efficiencies had been developed to become a parabola with the change of reaction time under a certain NH 3 /NO mole ratio and under a certain temperature and that denitration efficiencies also had changed to become a parabola with the increase of the reaction temperature when a NH 3 /NO mole ratio was identified. Denitration efficiencies of 91.6 percent could be reached when the optimal NH 3 /NO mole ratio, optimal reac tion temperature, and reaction time respectively were 1.2, 320 °C and 14min in this work.
