Oxidační katalyzátory pro snížení hmotnostních koncentrací znečišťujících látek ve spalinách

Abstract

The thesis focuses on the verification of the efficiency of oxidation honeycomb catalysts for the reduction of pollutant concentrations in the flue gas of small biomass combustion plants. In the first part, the theoretical basis of catalytic oxidation and its importance in terms of air protection are described. This is followed by an experimental part in which different types of prototype catalysts are tested first in model flue gases and then the selected catalyst was verified in real operation of the combustion plant. The results show differences in CO conversion efficiency under different operating conditions. The work also includes the design of a structural element for the installation of the catalyst in the flue gas duct, which enables the control of the flue gas bypass and the measurement of the pressure drop.
