Abstract
Paraffin cuts contaminated with aromatic compounds are brought in contact at ambient temperature with faujasites, in which the Si/Al ratio is less than 1.2, in particular, sodium faujasites which were partially exchanged with lithium. Thus, one can obtain purified cuts which are practically totally free from aromatic contaminants.
