A process is provided for producing a high quality lubricating oil base stock with a catalyst having a high viscosity index selectivity and low fouling rate. The catalyst contains a low amount of zeolite, and has a pore size distribution characterized by a significant amount of large pores.
L'invention concerne un procédé pour produire une matière de base d'huile de lubrification de haute qualité avec un catalyseur présentant une forte sélectivité de l'indice de viscosité et un faible taux d'encrassement. Le catalyseur contient une faible quantité de zéolithe et une répartition de la taille des pores caractérisée par une quantité significative de pores de grande taille.
