The kinetic data gathered from the previous study of the FeOx/Al2O3 catalyst displaying only medium activity were used as the input data. A single-channel 3D model without additional simplifications of fluid flow patterns and mass transfer in fluid and solid catalyst phases was employed to investigate the potential performance of a monolith reactor for N2O decomposition at high temperature regime. The model clearly predicted a relevant performance of the optimized honeycomb system based on such FeOx/Al2O3 catalyst. Workplace J.
