The results of investigation of adsorption properties of the MnBaSrLaCe catalyst on (γ+θ)/ Al2O3 by TPD of oxygen method are presented in paper. The presence adsorbed slightly bounded oxygen (Т1–Т2=473–773К, Еdes. = 80kJ/mol) and structural oxygen for MnBaSrLaCe/2%Ce/ Al2O3 catalysts separating out by means of destruction of Mn2O3 and Mn perovskites to Mn3O4(Т1–Т2=723–923, Еdes. = 98,6kJ/mol) and Mn3O4, MnO (Т1–Т2=923–1173, Еdes. = 115–142 kJ/mol). Maintenance of it sharply decreased at heating; Тмax of desorption moves to Т=1073К at which oxygen is allocated from manganese hexaaluminate.
