REACTION MECHANISM OF NO-NH3-O2 SYSTEM, ELUCIDATED BY TRANSIENT RESPONSE TECHNIQUE

[摘要] References(16)Cited-By(2)Transient response technique was applied to elucidate the roles of oxygen in NO-NH3-O2 reaction system at low concentrations of NO and NH3 (ca. 500 ppm). Reaction hardly takes place in the absence of oxygen. Analyses of transient response curves of such reaction system indicated that the reaction involves consumption of surface oxygen. High activity of CuSO4-Active Carbon catalyst is due to its high affinity for oxygen.
