METHOD FOR CONVERTING FEEDSTOCKS COMPRISING A HYDROTREATMENT STEP, A HYDROCRACKING STEP, A PRECIPITATION STEP AND A SEDIMENT SEPARATION STEP, IN ORDER TO PRODUCE FUEL OILS

摘要

The invention relates to a method for treating a hydrocarbon feedstock, said method comprising the following steps: a) a hydrotreatment step, in which the hydrocarbon feedstock and hydrogen are brought into contact on a hydrotreatment catalyst, b) an optional step of separating the effluent resulting from hydrotreatment step a), c) a step of hydrocracking at least part of the effluent resulting from step a) or at least part of the heavy fraction resulting from step b), d) a step of separating the effluent resulting from step c), e) a step of precipitating sediments, f) a step of physically separating sediments of the heavy liquid fraction resulting from step e), g) a step of recovering a liquid hydrocarbon fraction having a sediment content, measured according to the method of ISO 10307-2, which is less than or equal to 0.1% by weight.
