Method for the purification of a plastic liquefaction oil composition in a turbulent flow, and use thereof

Abstract

Method for purifying a composition comprising a plastic liquefaction oil, comprising: a) providing a composition comprising a plastic liquefaction oil containing at least 20 ppm by mass of heteroatoms, b) putting said composition in contact with an aqueous medium with a pH above 7, the putting in contact being implemented in turbulent regime having a Reynolds number higher than 2000 and at a temperature of less than or equal to 250° C. to obtain an effluent containing the modified composition, c) subjecting the effluent from step (b) to (c1) a washing in the presence of water or of a solvent that is not miscible with the purified composition, (c2) a separation, or to the succession of steps (c2) and (c1), and obtaining a purified composition having a reduced heteroatom content, and a phase containing the basic compound containing the basic com-pound and heteroatoms initially contained in the modified composition.
