Sažetak
Recently, more and more attention has been paid to the application of process intensification methodology, and accordingly, the possibility of applying additive manufacturing technology or 3D-printing to the manufacture of advanced versions of catalysts and chemical reactors using different materials is being studied. Considering that it is possible to create computer-optimized reactors using additive manufacturing techniques, it is easy to see the enormous potential this technique offers, especially on a laboratory scale. In this research, the analysis and modelling of a 3D-printed ceramic monolithic reactor fabricated by stereolithography was performed, while the deposition of the catalytically active layer was done using the wet impregnation technique. Their effectiveness was tested by the catalytic oxidation of BTEX compounds consisting of benzene (C6H6), toluene (C6H5CH3), ethylbenzene (C6H5CH2CH3), and xylene (C6H4(CH3)2). BTEX are aromatic hydrocarbons that occur in the environment as compounds naturally found in the oil. However, they are most commonly found in the atmosphere, where they can have harmful effects not only on the environment but also on living organisms and humans. A one-dimensional (1D) heterogeneous reactor model is proposed to model the reactor, which includes a kinetic model for the first-order reaction. The results obtained with the BTEX mixture and individual BTEX compounds were compared. The evaluation of the acceptability of the proposed model based on the corresponding values of the root of the standard deviation between the experimentally determined and the theoretically predicted values showed that the proposed model successfully describes the experimental results. Considering that the 1D heterogeneous model was derived based on the associated balances for model components in the gas phase and the balance for model components on the surface of the catalytic layer, which corresponds to the physical picture of the process, it was concluded that the proposed model is suitable for describing the catalytic oxidation of BTEX and similar aromatic volatile organic compounds using heterogeneously structured catalysts.
