Zusammenfassung:The present invention relates to a process for treating an SRF and/or plastics pyrolysis oil, comprising:a) optionally, selective hydrogenation of the feedstock;b) hydroconversion in an ebullated bed, in an entrained bed and/or in a moving bed, to obtain a hydroconverted effluent;c) separation of the hydroconverted effluent in the presence of an aqueous stream, to obtain a gaseous effluent, an aqueous liquid effluent and a liquid hydrocarbon effluent;d) fractionation of the liquid hydrocarbon effluent to obtain at least one gas stream and a cut with a boiling point of less than or equal to 385° C. and a cut with a boiling point above 385° C.;e) hydrotreatment of said cut comprising compounds with a boiling point of less than or equal to 385° C. to obtain a hydrotreated effluent;f) separation to obtain at least a gaseous effluent and a hydrotreated liquid hydrocarbon effluent.
