Summary:A process for the preparation of Group II and Group III lube oil base stocks wherein liquid-continuous aromatics saturation is used to treat lube hydrocrackate. The treated hydrocrackate is then be sent to dewaxing unit and then optionally to a hydrotreating step. La présente invention concerne un procédé de préparation d'huiles de base pour huile de lubrification du groupe II et du groupe III, la saturation des aromatiques en phase liquide continue étant utilisée pour traiter le produit d'hydrocraquage d'huile de lubrification. Le produit d'hydrocraquage traité est ensuite envoyé à une unité de déparaffinage puis facultativement à une étape d'hydrotraitement.
