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

摘要

The present invention relates to a treating method of hydrocarbon-containing feedstock comprising: a) a fixed-bed hydrotreating step; b) a separation step which optionally separates effluences originated from step a); c) a hydrocracking step of at least part of effluences originated from step a) or at least part of heavy fractions originated from step b); d) a separation step of effluences originated from step c); e) a maturation step of heavy liquid fractions originated from step d); and f) a sediment separation step from heavy liquid fractions originated from step e).
