SULPHOXIDATION CATALYSTS AND METHODS AND SYSTEMS OF THEIR APPLICATION Russian patent published in 2013 - IPC C10G27/10 C10G27/12 B01J21/06 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to sulphoxidation method of hydrocarbons, which involves hydrocarbon flow including at least one sulphur compound; oxidiser; catalyst including the metal compound represented with general formula M_mO_m(OR)_n; and bringing into contact of hydrocarbon flow with oxidiser in presence of catalyst, thus causing the oxidation of at least one sulphur compound, where M represents metal complex, R represents carbon group having at least 3 carbon atoms, where at each occurrence of R, the latter represents a replaced alkyl group containing at least one OH group, replaced cycloalkyl group containing at least one OH group, replaced cycloalkylalkyl group containing at least one OH group, replaced heterocyclyl group containing at least one OH group, or heterocyclylalkyl containing at least one OH group, subindices "Type" represent integer numbers of approximately 1 to approximately 8. Invention also refers to other methods of sulphoxidation of hydrocarbons, polymer catalytic composition for sulphoxidation of hydrocarbons, which catalyses sulphoxidation to hydrocarbon sulphoxidation reagent.

EFFECT: economic and effective catalytic desulphurisation of sulphur-containing flows of hydrocarbons.
