LIGHT PARAFFIN DEEP OXIDATION PROCESS Russian patent published in 2007 - IPC C07C9/00 

FIELD: petrochemical processes.

SUBSTANCE: invention relates to complete oxidation of light paraffins (methane, propane) into carbon dioxide and water of heterogeneous catalysts. Process comprises passing inert gas-diluted oxygen/paraffin stream through catalyst bed at 350 to 1000°C, said catalyst being geometrically structured system including (i) microfibers of high-silica fibrous carrier characterized by hydroxyl group IR absorption band with wave number ν=3620-3650 cm^-1 and half-width 65-75 cm^-1, specific surface as measured by BET method involving heat desorption of argon S_Ar=0.5-30 m²/g, surface value as measured by alkali titration method S_Na=5-150 m²/g at ratio S_Na/S_Ar=5-50, and (ii) at least one active element capable of forming charged either metallic, or bimetallic clusters characterized, in UV-Vis diffusion reflection spectrum, by specific bands in the region of 34000 to 42000 cm^-1 and ratio of integral intensity of band caused by charged metallic or bimetallic clusters to the same band caused by, respectively, metallic or bimetallic clusters at least 1.0..

EFFECT: optimized catalyst composition.
