Abstract: Method for purifying a composition comprising a plastic liquefaction oil comprising a treatment by a strong base in the presence of water followed by washing with water. The method is useful for reducing the concentration of heteroelements and in particular of alkali or alkaline earth metal cations in said composition with a view to making it compatible for introduction as a feedstock in conversion methods such as steam cracking, catalytic cracking on a fluidised bed, catalytic hydrogenation or hydrocracking, in particular without deactivation of catalysts used in these methods.

Abstract: A method for purifying a composition comprising a plastic pyrolysis oil comprising a treatment with a strong base in the solid state and washing with water. The method is useful for reducing the concentration of heteroelements in said composition with a view to making it compatible for introduction as feedstock in conversion methods such as steam cracking, fluid catalytic cracking, catalytic hydrogenation or hydrocracking.
