Environmental pollution is a problem that is getting more and more attention nowadays. Due to the sudden industrial development and the increasing intensity of anthropogenic activities there is an increasing number of pollutants in the environment. Volatile organic compounds, which under normal pressure and temperature conditions easily evaporate, are one of the most significant groups of compounds that cause atmospheric pollution. There are numerous methods to prevent the release of volatile organic compounds into the environment. Catalytic oxidation proved to be a promising process for the degradation of volatile organic compounds and one of the most efficient and economically most acceptable processes for their oxidation / decomposition. The aim of this work was the development of a ceramic monolithic catalyst for catalytic oxidation of aromatic volatile organic compounds. The development of the catalyst involved the application of catalytically active components to inert monolithic carriers, in which a commercial inert monolithic carrier (cordierite) was used in the first case. In the other case a crystalline monolithic carrier was prepared by 3D printing technology (or additive manufacturing). In both cases mixed manganese and copper oxide were used as a catalytically active component, which in previous studies showed high efficiency in similar experimental systems. Studies were conducted using toluene as a single component and mixture of organic compounds containing benzene, toluene, ethylbenzene and xylene (BTEX). The reactions were carried out at different temperatures and a constant total flow of the reaction mixture. During the work there was also a comparison of activity of the prepared catalyst with the activity of a commercial monolithic catalyst, which in its composition contained noble metals as a catalytically active component. The experiment showed that additive manufacturing can be successfully used for the preparation of monolithic catalysts for catalytic oxidation of volatile organic compounds. During the whole process cordierite monolithic and crystalline monolithic carriers with the MnCuOx layer proved to be effective catalysts for benzene, toluene, ethylbenzene and o-xylene oxidation. It was established that prepared monolithic catalysts can be used as a substitute for expensive commercial catalysts containing heavily accessible and expensive noble metals.
