In this work a new bench scale setup is presented that enables studies of the underlying processes of
ammonia oxidation under industrial, mass transfer controlled conditions by spatially resolved profile
measure ments. Measurements in the developed profile reactor are compared with computational fluid
dynamics simulations of ammonia oxidation to explain the measured phenomena and to validate the
surface kinetic model used in the simulations. All in all, the develo ped approach presented in this work
allows to spatially resolve the processes in ammonia oxidation under industrial conditions providing a
wealth of data for future process optimization.
