Commercial VOC oxidation catalysts can be used as comparative materials during development of new or improved catalysts. The objective of this study was to investigate physicochemical properties of EnviCat® commercial catalysts and their performance in total oxidation of three model compounds (dichloromethane, toluene and ethanol) at laboratory scale. The reactivity of model VOC was decreasing in the order ethanol > toluene > dichloromethane. The Cu-Mn/Al catalyst was found to be the most active and selective catalyst in ethanol oxidation. In oxidation of dichloromethane, the Pt-Pd/Al-Ce catalyst with 0.10 wt. % Pt+Pd was the most active, while the most selective one (giving the highest HCl yield) was the Pt-Pd/Al catalyst containing 0.24 wt. % Pt+Pd. In toluene oxidation, the Pt-Pd/Al catalyst with 0.24 wt. % Pt+Pd possessed the highest activity; the selectivity to CO2 was 100 % for all investigated catalyst.
