METHOD FOR OIL FRACTIONS HYDROCONVERSION AS PER SLURRY-TECHNOLOGY THAT ENSURES EXTRACTION OF METALS, CATALYST AND RAW STOCK INCLUDING STAGE OF COKING Russian patent published in 2015 - IPC C10G49/12 C10G67/02 B01J38/48

Abstract RU 2570200 C2

FIELD: oil and gas industry.

SUBSTANCE: invention is related to method for hydroconversion of heavy oil fractions that includes stage of raw stock hydroconversion at least in one reactor containing suspended catalyst and allows recuperation of metals from non-converted bottom fraction, in particular metals used as catalysts. The method includes stage of hydroconversion, stage of gas/fluid separation, coking stage, burning stage, stage of metals extraction and stage of preparation of catalyst solutions, which are recirculated at stage of hydroconversion.

EFFECT: very high degree of metals extraction for the purpose of their further usage.
