Sažetak
The monolithic reactors have been widely used to reduce emissions of undesired products and by- products of combustion. The advantages they offer, when compared with conventional multi-phase reactors (slurry and packed-bed reactors) have led to their use in many applications such as cleaning of automotive exhaust gases, selective catalytic reduction of nitrogen oxides, catalytic abatement of volatile organic compounds from industrial processes, catalytic fuel combustion, steam reforming of hydrocarbons etc. This work describes the research aimed at developing mathematical model for predicting the performance of a monolith reactor. Two heterogeneous models were applied to describe a single channel of the reactor. Comparison between the mass transfer coefficients, obtained using the model with 1D description of the gas phase and 2D description of the solid phase and a complete 2D model (2D description of both gas and solid phase) was made and discussed. The proposed models were verified by comparing the experimental data with theoretical predictions. Generally, a good agreement between the experimental data and theoretical prediction was obtained for both models due to adjustable parameters. Different values obtained with the two applied models for the interphase mass transfer coefficients could be attributed to different assumptions made during development of the models. In the future work particular emphasis will be put on providing suitability of such reactor models.
