Pseudo-homogeneous one-dimensional model of an ideal plug flow reactor was used for modeling of N2O decomposition in a laboratory fixed bed reactor filled with grains or pellets of a Co–Mn–Al mixed oxide catalyst. Increase in inlet pressure up to 0.6 MPa did not influence the effective diffusion coefficient, but improved the achieved N2O conversion. Based on the laboratory data of N2O decomposition over Co–Mn–Al mixed oxide pellets, catalyst bed of 3400 kg was estimated for target 90% N2O conversion (30 000 m3 h−1 of exhaust gases from HNO3 plant containing 0.1 molar% N2O, 0.01 molar% NO, 0.01 molar% NO2, 3 molar% H2O, 5 molar% O2) at 420 °C and 600 kPa inlet pressure.
