Oil conversion process loads comprising a step of hydrocracking bubbling bed, a maturing stage and a separation step of sediments for the production of fuel oil with a low sediment content

摘要

Method of converting a hydrocarbon feed comprising at least one hydrocarbon fraction having a sulfur content of at least 0.1% by weight, an initial boiling point of at least 340 ° C and a final boiling point of at least 440 ° C which allows for a heavy fraction having a sediment content after aging exceeding 0.1% by weight, said process comprising the following steps: a) a step of hydrocracking of the charge in presence of hydrogen in the least one reactor containing a catalyst supported ebullated bed, b) a step of separating the effluent obtained at the end of step a) in at least one light fraction containing hydrocarbon base fuel and a heavy fraction containing compounds boiling to at least 350 ° c, c) a maturing stage of the heavy fraction resulting from step b) separation which allows the transformation of a pair you potential sediment existing sediment performed for a duration between 1 and 1500 minutes, at a temperature between 50 and 350 ° C and at a pressure below 20 MPa, d) a separation step sediment of the resulting heavy fraction step c) maturation for said heavy fraction.
