Abstract
Catalytic characteristics of Mn-catalysts supported on different (SiO2 and BEA zeolite) were compared in the ozone decomposition and ozone-catalytic oxidation (OZCO) of VOCs using n-butane as the model compound. The parent SiO2 did not show any activity; therefore the characteristics of Mn/SiO2 are determined by the catalytic properties of the supported MnOx oxide. In contrast to SiO2, BEA zeolite demonstrates significant catalytic activity, though at a temperature by 50°C higher than Mn/BEA. The data obtained allow us to conclude that the catalytic characteristics of Mn/BEA at 30–100°C are determined by the Mn component of the catalyst. At higher temperature the catalytic properties of BEA can significantly affect the course of the OZCO process. The zeolite carrier improves hydrocarbon conversion at 100–200°C and decreases the amount of ozone required for the OZCO process over Mn/BEA.
