Decomposition and O₃-Catalytic Oxidation of n-С₄Н₁₀

The activity of transition metal oxides (V, Cr, Mn, Fe, Co, Ni, Cu, Zn) deposited on γ-Al₂O₃ in the ozone decomposition reaction has been studied. The catalytic characteristics of samples with high (NiO/Al₂O₃), low (Cr₂O₃/Al₂O₃) and intermediate (MnO_x/Al₂O₃) activity in ozone decomposition were studied in the process of ozone-catalytic oxidation (OZCO) of butane. The obtained results allow us to conclude that the optimal activity of transition metal oxide in the decomposition of O₃ is of key importance in the OZCO process. At a low rate of ozone decomposition, the oxidation of hydrocarbons is limited by the rate of formation of atomic oxygen, in the case of too high - the conversion of hydrocarbons is reduced due to the “inappropriate” process of recombination of atomic oxygen. The best catalytic characteristics in the oxidation of h C₄H₁₀ have been established for a catalyst based on Mn oxide, which has optimal activity in the decomposition of O₃.
