METHOD FOR OIL FRACTIONS HYDROCONVERSION AS PER SLURRY-TECHNOLOGY THAT ENSURES EXTRACTION OF METALS, CATALYST AND RAW STOCK INCLUDING STAGE OF COKING

摘要

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.12 cl, 2 dwg
