A catalyst for hydrotreating gas oil, which comprises an inorganic oxide support having provided thereon: at least one selected from metals in the Group 6 of the periodic table at from 10 to 30% by weight, at least one selected from metals in the Group 8 of the periodic table at from 1 to 15% by weight, phosphorus at from 1.5 to 6% by weight, and carbon at from 2 to 14% by weight, each in terms of a respective oxide amount based on the catalyst, wherein the catalyst has a specific surface area of from 220 to 300 m2/g, a pore volume of from 0.35 to 0.6 ml/g, and an average pore diameter of about from 65 to 95 .ANG.; a process for producing the catalyst; and a method for hydrotreating gas oil, which comprises subjecting a gas oil fraction to a catalytic reaction in the presence of the catalyst under conditions at a hydrogen partial pressure of from 3 to 8 MPa, a temperature of from 300 to 420°C, and a liquid hourly space velocity of from 0.3 to 5 hr-1.

L'invention concerne un catalyseur pour hydrogénation d'un gas-oil. Ce catalyseur comprend un support oxyde inorganique, lequel comporte de 10 à 30 % en poids d'au moins un métal choisi dans le groupe 6 du tableau périodique, de 1 à 15 % en poids d'au moins un métal choisi dans le groupe 8 du tableau périodique, de 1,5 à 6 % en poids de phosphore et de 2 à 14 % en poids de carbone, les pourcentages étant relatifs au poids du catalyseur et exprimés en termes d'oxydes des métaux respectifs. Ce catalyseur possède une surface spécifique de 220 à 300 m<2>/g, un volume poreux de 0,35 à 0,6 ml/g, un diamètre poreux moyen de 65 à 95 ANGSTROM . L'invention concerne également un procédé de préparation dudit catalyseur ainsi qu'un procédé d'hydrogénation d'un gas-oil qui consiste à effectuer une réaction catalytique d'une fraction de gas-oil en présence d'un catalyseur, dans des conditions où la pression partielle de l'hydrogène est de 3 à 8 MPa, la température de réaction de 300 à 420 DEG C et la vitesse spatiale des liquides de 0,3 à 5 hr<-1>.
