Air pollution due to accelerated industrialization is a growing problem in the world and is at the center of numerous studies. Volatile organic compounds (VOC) are known toxic compounds that contribute to air pollution and evaporate very easily under normal conditions of pressure and temperature. The most important representatives of volatile organic compounds, benzene, toluene, ethylbenzene and o-xylene (BTEX), are dangerous to human health, flora and fauna, and depending on the duration of exposure cause acute and chronic problems. There are numerous methods for reducing emissions of volatile organic compounds into the environment, with catalytic oxidation being singled out as one of the most effective methods. The aim of this work is to develop a ceramic monolithic catalyst for the catalytic oxidation of VOC, using a gaseous mixture of benzene, toluene, ethylbenzene and o-xylene (BTEX) as a model component. The technique of additive production (or 3D-printing) was used to produce the monolithic catalyst carrier. Catalytic active components (combinations of transition metals manganese, copper, iron) were applied to monolithic carriers by the method of impregnation. Catalytic oxidation of BTEX was performed at a constant initial concentration of the model components, a constant ratio of reactant and oxidant (synthetic air) and at different temperatures and space times. It was found that the technology of additive production (3D-printing), i.e. the process of stereolithography, makes it possible to successfully produce ceramic monolithic carriers of the catalytically active components. It was established that the conversion of BTEX components increases with the increase of reaction temperatures and with the decrease of total flow of reaction mixture, that is with the increase of space time. A good matching of the experimental results on the assumed 1D heterogeneous reactor models including the first order kinetic reaction models for all components of the BTEX mixtures is obtained. The values of key model parameters, i.e. values of reaction rate constants, k, activation energy, Ea and significant frequency (Arrhenius characteristics), Ar for both catalysts were estimated and it was concluded that MnCuOx is an effective catalyst for oxidation of BTEX from MnFeOx.
