FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to the method of hydroconversion of heavy oil fractions comprising a stage of hydroconversion of raw materials at least in one reactor containing the suspended catalyst. The method includes a hydroconversion stage, a gas/liquid separation stage, an extraction liquid/liquid stage, a crushing stage, a washing stage, a burning stage, a metal extraction stage and a stage of preparation of catalytic solutions which are recirculated at the hydroconversion stage.
EFFECT: recovery and recycling of metals separated from catalysts and heavy fractions during hydroconversion process.
