Abstract: The hydrodynamics and the mass-transfer impact of the three-phase trickle-bed reactor performance in an environmental application of phenol catalytic wet oxidation is described. The activities of both the CuO-supported catalyst and the extruded active carbon were compared. To avoid liquid maldistribution, also the bed of catalyst particles with void fraction diluted by fine glass spheres was used. Under the conditions of the gas component transfer limitation, a better wetting of the catalyst can lead to the worse reactor performance due to lower reaction rates.
