Feedstock conversion method for producing fuel oil comprising a hydrotreating step, a hydrocracking step, a precipitation step, and a precipitate separation step

摘要

The present invention relates to a method for treating a hydrocarbon feed, said method comprising the following steps: a) a hydrotreating step; in this step, the hydrocarbon feed and hydrogen are brought into contact with a hydrotreating catalyst, b ) Optional step of separating the effluent from hydroprocessing step a), c) at least a portion of the effluent from step a) or at least a portion of the heavy fraction from step b). A step of decomposing, a step of separating the effluent derived from step c), e) a step of precipitating the precipitate, and f) a step of physically separating the precipitate of the heavy liquid fraction derived from step e). And g) recovering a liquid hydrocarbon fraction having a sediment content measured by the method of ISO 10307-2; 0.1% by weight or less.
