OIL PROCESSING METHOD Russian patent published in 2013 - IPC C10G7/00 C10G65/04 C10G69/06 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil processing industry. The invention is related to oil processing method that includes oil fractionating with production of benzene fraction, light gasoil cut, heavy gasoil cuts and residue; thermal conversion of light gasoil cuts with production of heavy residue of thermal conversion, benzene fraction and light gasoil cut of thermal conversion; hydraulic treatment of the amount of light gasoil cuts and benzene fractions with production of respective hydrogenation products; and stabilisation of hydrogenation products of the amount of light gasoil cuts with production of fuel oil; at that the amount of residues of fractioning and thermal conversion are is subject to hydroconversion with obtainment of hydrogenation products divided into benzene fraction, light gasoil cut and residue drained as boiler fuel for auxiliaries while hydrogenation products of the amount of benzene fractions in result of fractioning, thermal conversion and hydroconversion are subject to catalytic processing in presence of zeolite-containing catalyst with subsequent fractioning of the product and production of stable high-octane petrol; at that the amount of light gasoil cuts in result of fractioning, thermal conversion and hydroconversion is sent to hydraulic treatment.

EFFECT: improvement of ultimate yield of engine fuel and fuel oil, improvement of petrol quality.
