Summary:The invention relates to a process for treating plastic pyrolysis oil, comprising: a) selective hydrogenation of said feedstock in the presence of at least hydrogen and at least one selective hydrogenation catalyst; b) hydrotreating the hydroprocessing effluent in the presence of at least hydrogen and at least one hydrotreating catalyst to obtain a hydrotreated effluent; c) hydrocracking the hydrotreated effluent in the presence of at least hydrogen and at least one hydrocracking catalyst to obtain a hydrocracked effluent; d) separation of the hydrocracking effluent in the presence of the aqueous stream at a temperature of 50-370 DEG C to obtain at least one gaseous effluent, an aqueous liquid effluent and a hydrocarbon-based liquid effluent. 本发明涉及用于处理塑料热解油的方法,其包括:a)在至少氢气和至少一种选择性加氢催化剂存在下的所述原料的选择性加氢;b)在至少氢气和至少一种加氢处理催化剂存在下的所述加氢流出物的加氢处理,以获得加氢处理流出物;c)在至少氢气和至少一种加氢裂化催化剂存在下的所述加氢处理流出物的加氢裂化,以获得加氢裂化流出物;d)在水性物流存在下,在50-370℃的温度下的加氢裂化流出物的分离,以获得至少一个气态流出物、水性液体流出物和基于烃的液体流出物。
