Catalytic performance of mixed Mn-M (M: Fe, Ni, Cu) oxides in toluene oxidation

Volatile organic compounds (VOCs) are recognized as the major contributors to global air pollution and the development of the effective methods and materials for the abatement of VOCs became of great importance. Catalytic oxidation is the most promising technology for VOC abatement and most of the catalysts used for this purpose are, generally, very active but also very expensive noble metals (Pt, Pd, etc). Therefore, many efforts have been made towards the design of cheaper catalyst materials based on the mixed transition metal oxides. This paper deals with preparation, characterization and catalytic activity of the mixed manganese oxides, Mn-M (M: Fe, Ni, Cu) used for catalytic oxidation of toluene. Catalysts were synthesized by the coprecipitation method and various instrumental techniques were used for their characterization. Catalytic tests were performed in the fixed bed flow reactor. The influences of different reaction conditions on the catalytic performance were examined using gaseous mixture of toluene and nitrogen (242ppm of toluene/nitrogen) and air as an oxidant. Tests were performed at different temperatures (373-675K) and various total flow rates of the reaction mixture (23-138cm3/min) at the constant catalyst mass (0.05g). Obtained mesoporous catalysts show high low- temperature activities for the toluene oxidation with T90 temperatures, corresponding to 90% of the toluene conversion, observed at 450K and even lower temperatures.
