FIELD: oil and gas industry.SUBSTANCE: invention relates to the method of the hydroconversion of heavy oil fractions, including stage of the raw stock hydroconversion in at least one reactor, containing suspended catalyst, ensuring the ability for metals recuperation from the residual unconverted fraction, in particular used as catalyst. The method includes stage of the hydroconversion, stage of gas/liquid separation, at least one stage of extraction liquid/liquid, combustion stage, stage of metals extraction, and stage of catalytic solutions making, that circulate to stage of the hydroconversion.EFFECT: recuperation and return to cycle of all metals escaped from catalysts and heavy fractions.13 cl, 3 dwg |
