“…The peculiarity of the proposed solution was the use of the calculated catalytic reactor in conditions of large volumes of flue gases and low CO concentrations at the companies of electrode production. Additionally, the use of an inert material (zeolite) does not promote the loss of carbon material, while the application of manganese dioxide on the backfill of the electrodes accelerates the carbon oxidation, which is an undesirable process [19]. The advantages of the obtained oxide-metal catalyst system are cheapness and availability compared to the use of noble metals.…”

The article highlights the development of cheap affordable highly efficient catalytic oxidation system of harmful components of industrial flue gases of carbon graphite enterprises, its design features according to the parameters of furnace equipment, which will significantly improve the environmental safety of metallurgical and machine-building enterprises. The presented calculation and design solutions, in addition to carbon production, can be used in environmental protection technologies at other environmentally hazardous facilities to neutralize toxic emissions. The paper presents the calculation of the catalytic CO oxidation reactor made for the real flow rate of flue gases with temperature range 270−390 ºC, which come out of the combustion chamber of the Riedhammer "first fire" kiln, heated by the flue gases. For such medium exothermic processes, mass and heat transfer between gas flow and the outer surface of the catalyst grains is sufficient intense. In this case for description of the catalytic process in the reactor is sufficient to use quasi-homogeneous single-phase model. The model of plug-flow reactor with a fixed bed of catalyst was used to calculate the flow parameters of the gas mixture through a reactor loaded with a composite zeolite-based manganese-oxide catalyst in the process of catalytic CO oxidation. The calculation results obtained using the software CHEMCAD 7.1.5 were almost identical to the previously made calculation. The peculiarity of the suggested solution was the use of the designed catalytic reactor for treatment of large volume of flue gases with low concentrations of CO at the companies of electrode carbon graphite production
