METHOD FOR TREATING PLASTIC PYROLYSIS OILS INCLUDING A HYDROGENATION STEP AND A HOT SEPARATION

The present invention relates to a method for treating a plastic pyrolysis oil, comprising: a) hydrogenating said feedstock in a mixture with at least part of the liquid effluent resulting from step c) and in the presence of hydrogen and a catalyst at a temperature between 140 and 340°C; b) hydrotre...

Summary:The present invention relates to a method for treating a plastic pyrolysis oil, comprising: a) hydrogenating said feedstock in a mixture with at least part of the liquid effluent resulting from step c) and in the presence of hydrogen and a catalyst at a temperature between 140 and 340°C; b) hydrotreating said hydrogenated effluent in the presence of hydrogen and a catalyst; c) separating the hydrotreated effluent, said separation being carried out at high temperature and under high pressure in order to obtain a gaseous effluent and a liquid effluent, part of which is recycled upstream of step a); d) separating, carried out at low temperature and under high pressure and supplied with the gaseous effluent and the other part of the liquid effluent resulting from step c) and an aqueous solution, in order to obtain a hydrocarbon-based effluent.
