Abstract

A process for converting heavy petroleum feedstocks to produce fuel oils and fuel-oil bases with a low sediment content comprises: a) fixed-bed hydrotreatment, b) optional separation of the effluent originating from the hydrotreatment stage a), c) hydrocracking of at least a part of the effluent from a) or of at least a part of the heavy fraction originating from b), d) separation of the effluent originating from c), e) maturation of the heavy liquid fraction originating from the separation d), and f) separation of the sediments from the heavy liquid fraction originating from the maturation e).
