Abstract: 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.

Abstract: The invention relates to a polypropylene composition comprising: (a) a first metallocene-catalyzed polypropylene (RPP-A) which is homopolymer, or a random copolymer of propylene and of a co-monomer; and (b) a second metallocene-catalyzed polypropylene (RPP-B) which is a random copolymer of propylene and of a co-monomer; wherein said polypropylene composition has:- a total co-monomer content of at least 1.1% by weight relative to the total weight of said polypropylene composition, as determined by 13C NMR analysis, said co-monomer being an alpha-olefin different from propylene;- a melting temperature Tm of at least 130° C., measured by DSC; - a crystallization temperature Tc of at least 95.0° C., measured by DSC; - a ratio of weight average molecular weight (Mw) to number average molecular weight (Mn) [Mw/Mn] of at least 4.50;- a ratio of z-average molecular weight (Mz) to weight average molecular weight (Mw) [Mz/Mw] of at least 2.10; and- a co-monomer distribution ratio R(Mz)/R(Mn) higher than 0.
