Abstract

L'invention concerne un procédé de maîtrise de la masse molaire de produits de thermolyse à l'aide d'un fluide de refroidissement (par exemple, de l'eau) en vue de moduler les températures de condensation des produits finaux. Avec cette stratégie, la thermolyse du polyéthylène (PE) et du polypropylène (PP) est adaptée pour générer de l'huile liquide, sans aucun catalyseur ni additif. Le fait d'ajouter ultérieurement de l'acide sulfurique dans les groupes alcényle, puis de neutraliser par hydroxyde de sodium, permet d'obtenir des détergents au sulfate ayant un excellent comportement moussant.
