On traite ensuite le produit obtenu par l'hydrogène au contact d'un catalyseur renfermant au moins un métal de chacun des groupes VI.A et VIII à une température de 250 à 400.degree.C.  On traite enfin le produit à nouveau obtenu à 200-380.degree.C par l'hydrogène au contact d'un catalyseur renfermant 0,1-2 % en poids d'au moins un métal noble du groupe VIII, 0,5 à 15 % en poids de chlore ou de fluor et de l'alumine.  L'on recueille alors une fraction d'hydrocarbures hydrogénée et stabilisée.
