摘要： The invention concerns a process for converting a hydrocarbon feed, said process comprising the following steps: a) a step of hydrocracking the feed in the presence of hydrogen; b) a step of separating the effluent obtained from step a); c) a step of precipitating sediments, in which the heavy fraction obtained from the separation step b) is brought into contact with a distillate cut at least 20% by weight of which has a boiling point of 100° C. or more for a period of less than 500 minutes, at a temperature in the range 25° C. to 350° C., and at a pressure of less than 20 MPa; d) a step of physical separation of the sediments from the heavy fraction obtained from step c); e) a step of recovering a heavy fraction having a sediment content, measured using the ISO 10307-2 method, of 0.1% by weight or less.

摘要： The invention concerns a process for the treatment of a hydrocarbon feed, said process comprising the following steps: a) a hydrotreatment step, in which the hydrocarbon feed and hydrogen are brought into contact over a hydrotreatment catalyst, b) an optional step of separating the effluent obtained from the hydrotreatment step a), c) a step of hydrocracking at least a portion of the effluent obtained from step a) or at least a portion of the heavy fraction obtained from step b), d) a step of separating the effluent obtained from step c), e) a step of precipitating sediments, f) a step of physical separation of the sediments from the heavy liquid fraction obtained from step e), g) a step of recovering a liquid hydrocarbon fraction having a sediment content, measured using the ISO 10307-2 method, of 0.1% by weight or less.

摘要： The invention relates to a process for converting a hydrocarbon-containing feedstock containing at least one hydrocarbon fraction having a sulphur content of at least 0.1% by weight, an initial boiling temperature of at least 340° C. and a final boiling temperature of at least 440° C., making it possible to obtain a heavy fraction having a sediment content after ageing of less than or equal to 0.1% by weight, said process comprising the following stages: a) a stage of hydrocracking the feedstock in the presence of hydrogen in at least one reactor containing a supported catalyst in an ebullating bed, b) a stage of separating the effluent obtained at the end of stage a), c) a stage of maturation of the heavy fraction originating from the separation stage b), d) a stage of separating the sediments from the heavy fraction originating from the maturation stage c) to obtain said heavy fraction.
