PROCEDE DE CONVERSION DE CHARGES PETROLIERES COMPRENANT UNE ETAPE D'HYDROTRAITEMENT EN LIT FIXE, UNE ETAPE D'HYDROCRAQUAGE EN LIT BOUILLONNANT, UNE ETAPE DE MATURATION ET UNE ETAPE DE SEPARATION DES SEDIMENTS POUR LA PRODUCTION DE FIOULS A BASSE TENEUR EN SEDIMENTS.

摘要

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).
