Heat transfer experiments with and without chemical reaction were performed in a wall-cooled tubular reactor. The oxidation of carbon monoxide over a CuO/γ-alumina catalyst was used as a model reaction. A two-dimensional heterogeneous reactor model was used for calculation of the temperature and concentration profiles inside the packing. The experiments were performed at Re between 200 and 1400, reactor pressures of 3, 5.9 and 8 bar, wall temperatures of 156, 180 and 200 °C and CO inlet concentrations ranging from 0.1 to 1.5% vol. The obtained data show that a radial distribution of the axial fluid velocity should be taken into account to reconcile the effective heat transport parameters obtained from experiments with and without reaction.
