The activity of transition metal (V, Cr, Mn, Fe, Co, Ni, Cu, and Zn) oxides supported on γ-Al2O3 in the reaction of ozone decomposition was studied. The catalytic characteristics of the samples with high (NiO/Al2O3), low (Cr2O3/Al2O3), and intermediate (MnOx/Al2O3) activity in ozone decomposition were studied in the process of ozone catalytic oxidation (OZCO) of n-butane. The results obtained allowed us to conclude that the optimal activity of a transition metal oxide in the decomposition of O3 is of key importance in the OZCO process. At a low rate of ozone decomposition, hydrocarbon oxidation is limited by the rate of formation of atomic oxygen species; at an excessively high rate of decomposition, hydrocarbon conversion decreases due to an competitive process of atomic oxygen recombination. The best catalytic performance in the oxidation of n-C4H10 was observed for a catalyst based on Mn oxide, which has an optimal activity in the decomposition of O3.
