PROCESS FOR CONVERTING PETROLEUM FEEDSTOCKS COMPRISING A STAGE OF FIXED-BED HYDROTREATMENT, A STAGE OF EBULLATING-BED HYDROCRACKING, A STAGE OF MATURATION AND A STAGE OF SEPARATION OF THE SEDIMENTS FOR THE PRODUCTION OF FUEL OILS WITH A LOW SEDIMENT CONTENT
PROCESS FOR CONVERTING PETROLEUM FEEDSTOCKS COMPRISING A STAGE OF FIXED-BED HYDROTREATMENT, A STAGE OF EBULLATING-BED HYDROCRACKING, A STAGE OF MATURATION AND A STAGE OF SEPARATION OF THE SEDIMENTS FOR THE PRODUCTION OF FUEL OILS WITH A LOW SEDIMENT CONTENT
The invention relates to a process for treating a hydrocarbon-containing feedstock comprising the following stages: a) a stage of fixed-bed hydrotreatment, b) an optional stage of separation of the effluent originating from the hydrotreatment stage a), c) a stage of hydrocracking of at least a part of the effluent from stage a) or of at least a part of the heavy fraction originating from stage b), d) a stage of separation of the effluent originating from stage c), e) a stage of maturation of the heavy liquid fraction originating from the separation stage d), f) a stage of separation of the sediments from the heavy liquid fraction originating from the maturation stage e).
