Summary:Title screen
The wet peroxide oxidation of phenol over the extruded 1.5%Cu/(80%H-ZSM-5 + 20%Al2O3) catalysts ofthe different geometric forms and sizes (cylinders with diameters 1, 2, 3 mm, trefoils, spheres and monolithswith size of channels 1.0 1.0, 1.5 1.5 mm) was studied in a flow reactor. The geometric form andsize of the catalyst granules exert a pronounced effect on the apparent kinetics of the process. The highestefficiency toward phenol destruction was observed for the catalysts with a greater geometric surface area(trefoils and monolith with high channel density). The conversions of phenol and TOC at flow rate5 mL min1 equal to 100 and 90% were achieved over these catalysts. Application of the spherical shapecatalyst with lowest geometric surface gave only 80% conversion of phenol at the same reaction conditions.The proposed mathematical model of the process, accounting for internal and external diffusionlimitations on the base of the pseudo-first order simplification of the apparent kinetic rates, provide reasonablyaccurate description of the experimental data and reproducing all important process regularities.
