The highest N2O conversion was reached over Ni-Al (Ni:Al = 4:2) and Co-Mn-Al (Co:Mn:Al = 4:1:1) catalysts. It was found that N2O conversion was decreased with increasing amount of oxygen and slightly decreased with NO in the feed. The presence of NO2 caused strong inhibition of reaction rate over the Ni-Al catalyst while no such decrease was observed over the Co-Mn-Al one. Water vapor inhibited the N2O decomposition over all tested catalysts. Based on the kinetic data, packed bed volume of the Co-Mn-Al catalyst necessary for N2O emissions abatement in HNO3 production plant was calculated as 35 m3 for waste gas flow rate of 30.000 m3 h-1.
