The present invention concerns a method for processing a plastic pyrolysis oil, comprising: a) a step of selective hydrogenation of the feedstock in the presence of hydrogen and at least one selective hydrogenation catalyst, at a temperature between 100 and 150°C, a partial pressure of hydrogen between 1.0 and 10.0 MPa absolute and an hourly space velocity between 1.0 and 10.0 h-1, in order to obtain a hydrogen effluent; b) a step of hydroprocessing said hydrogen effluent in the presence of hydrogen and at least one hydroprocessing catalyst, at a temperature between 250 and 370°C, a partial pressure of hydrogen between 1.0 and 10.0 MPa absolute and an hourly space velocity between 0.1 and 10.0 h-1, in order to obtain a hydroprocessing effluent; c) a step of separating the hydroprocessing effluent originating from step b) in the presence of an aqueous flow, said step being performed at a temperature between 50 and 370°C, in order to obtain at least one gaseous effluent, one aqueous liquid effluent and one hydrocarbon liquid effluent. |
