Abstract (en)

A method for eliminating the aromatic components at a content of 0.1-2% present in a paraffin consists of contacting at ambient temperature, the paraffin in the liquid state with a faujasite of ratio Si/Al less than 1.2.

Abstract (fr)

On contacte à température ambiante des coupes paraffiniques polluées de composés aromatiques avec des faujasites dont le rapport Si/Al 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.
