araffin sections polluted by aromatic compounds are brought into contact at ambient temperature with faujasites that have an Si/Al ratio lower than 1.2, particularly sodium faujasites partially displaced by lithium. This method makes it possible to obtain purified sections that are almost completely free of aromatic contaminants.

On contacte a température ambiante des coupes paraffiniques polluées de composés aromatiques avec des faujasites dont le rapport Si/AI est inférieur à 1,2, en particulier les faujasites sodiques partiellement échangées au lithium. On peut obtenir ainsi des coupes purifiées pratiquement totalement épurée de contaminants aromatiques.
