Abstract

L'invention concerne un procédé de purification d'un polypropylène recyclé. Le procédé comprend l'obtention de polypropylène recyclé, sa mise en contact avec un premier solvant fluide pour produire un polypropylène recyclé extrait, puis la dissolution du polypropylène recyclé extrait dans un solvant pour produire une première solution comprenant du polypropylène et des contaminants en suspension. La première solution est décantée pour produire une deuxième solution comprenant du polypropylène et des contaminants restants. La deuxième solution est purifiée par mise en contact de la seconde solution avec des milieux solides pour produire une troisième solution comprenant du polypropylène plus pur. Enfin, le polypropylène plus pur est séparé de la troisième solution.
