Beschreibung
Zusammenfassung:	The present invention relates to a process for treating a plastics pyrolysis oil, comprising:a) the selective hydrogenation of said feedstock to obtain a hydrogenated effluent;b) hydrotreatment of said hydrogenated effluent to obtain a hydrotreatment effluent;c) a first step of hydrocracking of said hydrotreated effluent to obtain a first hydrocracked effluent;d) separation of the hydrocracked effluent in the presence of an aqueous stream, to obtain a gaseous effluent, an aqueous liquid effluent and a hydrocarbon-based liquid effluent;e) fractionation of the hydrocarbon-based liquid effluent to obtain at least one gas stream and at least one naphtha cut and a heavier cut;f) a second step of hydrocracking of the heavier cut to obtain a second hydrocracked effluent;g) recycling of at least a portion of said second hydrocracked effluent into the separation step d).
