EFFECT OF STRUCTURAL, REDOX AND ACID CHARACTERISTICS OF MxOy/ZrO2(Al2O3) (M – Mn, Co, Cr) OXIDE NANOCOMPOSITES ON THEIR CATALYTIC PROPERTIES IN THE DEEP OXIDATION OF METHANE

Alumina- and zirconia-manganese catalysts for the deep oxidation of methane were studied by X-ray phase analysis, temperature-programmed hydrogen reduction, and IR spectroscopy. The most active catalyst has the optimal combination of dimensional, redox, and acid characteristics. The zirconia–manganese catalysts formed on the surface of a kaolin–aerosil honeycomb matrix provides for 80-100% conversion of methane to CO2 at 690-750 °C.
