A pseudo-homogeneous one-dimensional model of an ideal plug flow reactor under an isothermal regime (450 degrees C) was used for reactor design. A catalyst particle diameter of 3 mm is a compromise size because increasing the size of the catalyst particle leads to a decrease in the reaction rate because of an internal diffusion limitation, and particles with a smaller diameter cause a large pressure drop. A catalyst bed of 11.5 m(3) was estimated for the target N(2)O conversion of 90% upon the treatment of 30000 m(3)/h of exhaust gas (0.1 mol% N(2)O, 0.005 mol% NO, 0.9 mol% H(2)O, 5 mol% O(2)) at 450 degrees C and 130 kPa.
