摘要： The invention relates to a method for purifying a pyrolysis oil originating from the pyrolysis of waste including plastics by liquid/liquid extraction. This extraction is performed by means of a polar solvent that is immiscible with pyrolysis oil, for which a recovery rate is obtained greater than or equal to 0.95, this recovery rate being defined as the ratio of the extract volume over the initial volume of solvent, this extract being a phase containing the solvent which is immiscible with pyrolysis oil, recovered after agitation then decantation of a mixture of one part by volume of solvent with twenty-five parts by volume of pyrolysis oil at atmospheric pressure and at a temperature of 20° C.
