CATALYST, METHOD OF ITS PREPARATION AND METHOD OF METHANE OXIDATION Russian patent published in 2010 - IPC B01J23/745 B01J23/78 B01J23/889 C01F11/04 C07F15/02

Abstract RU 2388535 C1

FIELD: process engineering.

SUBSTANCE: invention relates to complete methane oxidation catalysts and can be used in industries using diesel fuel. Invention covers complete methane oxidation catalysts based on strontium hexaferrites of the following composition: SrMn_xFe_12-xO₁₉, where x=0, 1, 2, 6. Proposed method comprises settling catalyst components with the help of NH₄HCO₃ solution at constant pH equal to (7.1 to 8.0) and temperature not lower than 70°C with subsequent stages of filtration, rinsing, drying and roasting. Proposed method comprises also the stage of heat treatment at 800° to 1000° C and is realised in the presence of above described catalysts.

EFFECT: high degree of methane conversion at relatively low temperatures.
