A catalyst for conducting hydrodesulfurization and isomerization of a light hydrocarbon oil at the same time, which comprises a carrier comprising zirconium oxide or zirconium hydroxide, 1 to 3 mass % in terms of sulfur, relative to the total weight of the catalyst composition, of sulfate radical and, relative to the total weight of the catalyst composition, (I) 0.05 to 10 mass % of palladium, (II) 0.05 to 10 mass % of palladium and 0.05 to 10 mass % of platinum, or (III) 0.05 to 10 mass % of nickel, and has a specific surface area after burning and stabilization at 550 to 800 ~C of 50 to 150 m2/g; a method for preparation of the catalyst; and a method for hydrosulfurization isomerization of a light hydrocarbon oil using the catalyst.

L'invention concerne un catalyseur permettant l'hydrodésulfuration et l'isomérisation simultanées d'une huile hydrocarbure légère. Ledit catalyseur comprend un support comportant de l'oxyde de zirconium ou de l'hydroxyde de zirconium, 1 à 3 % en masse, en termes de soufre, par rapport au poids total de la composition du catalyseur, de radical sulfate, par rapport au poids total de la composition du catalyseur, (I) 0,05 à 10 % en masse de palladium, (II) 0,05 à 10 % en masse de palladium et 0,05 à 10 % en masse de platine, ou (III) 0,05 à 10 % en masse de nickel, et présente une surface spécifique après combustion et stabilisation à 550 à 800 ·C de 50 à 150m?2¿/g. L'invention porte également sur un procédé de préparation dudit catalyseur et sur un procédé d'hydrodésulfuration / isomérisation d'une huile hydrocarbure légère, au moyen dudit catalyseur.
