Sažetak
This paper is focused on development of the metal monolithic structure for total oxidation of toluene at low temperature. The well-adhered catalyst, based on the mixed oxides of manganese and nickel, is washcoated on the Al/Al2O3 plates as metallic support. For the comparison purposes, results observed for the manganese–nickel mixed oxide supported on the metallic monolith are compared with those obtained using powder type of the same catalyst. Prepared manganese–nickel mixed oxides in both configurations show remarkable low-temperature activity for the toluene oxidation. The reaction temperature T50 corresponding to 50% of the toluene conversion is observed at temperatures of ca. 400– 430 K for the powder catalyst and at ca. 450– 490 K for the monolith configuration. The appropriate mathematical models, such as one- dimensional (1D) pseudo-homogeneous model of the fixed bed reactor and the 1D heterogeneous model of the metal monolith reactor, are applied to describe and compare catalytic performances of both reactors. Validation of the applied models is performed by comparing experimental data with theoretical predictions. The obtained results confirmed that the reaction over the monolithic structure is kinetically controlled, while in the case of the powder catalyst the reaction rate is influenced by the intraphase diffusion.
