CA 2449623

The present invention pertains to a catalyst comprising 7-20 wt.% of a Group VIB metal component, calculated as trioxide on the weight of the catalyst, and 0.5 to 6 wt.% of a Group VIII metal component, calculated as oxide on the weight of the catalyst, on a porous inorganic carrier, said catalyst having a specific surface area of 100-180 m2/g, a total pore volume of at least 0.55 ml/g, at least 50% of the total pore volume in pores with a diameter of at least 20 nm (200 .ANG.), and 10-30% of the total pore volume in pores with a diameter of at least 200 nm (2000 .ANG.), and 0-1% of the total pore volume in pores with a diameter above 100 nm (1000 .ANG.). The catalyst is particularly suitable for the hydroprocessing of heavy hydrocarbon feeds of which at least 50 wt.% boils above 538 ~C (1000 ~F). It is especially advantageous for the hydroprocessing of feedstocks of which at least 80 wt.% boils above 538 ~C (1000 ~F).

La présente invention concerne un catalyseur comprenant de 7 à 20 % en poids d'un composant métallique du groupe VIB, calculé en tant que trioxyde sur le poids du catalyseur; et de 0,5 à 6 % en poids d'un composant métallique du groupe VIII, calculé en tant qu'oxyde sur le poids du catalyseur, sur un support inorganique poreux, ledit catalyseur présentant une surface active spécifique de 100 à 180 m?2¿/g, un volume de pores total d'au moins 0,55 ml/g, au moins 50 % du volume de pores total des pores présentant un diamètre d'au moins 20 nm (200 .ANG.), de 10 à 30 % du volume de pores total des pores présentant un diamètre au moins égal à 200 nm (2000 .ANG.), et de 0 à 1 % du volume de pores total des pores présentant un diamètre supérieur à 1000 nm (10000 .ANG.). Le catalyseur décrit dans cette invention convient tout particulièrement à l'hydrocraquage de charges d'hydrocarbure lourdes dont au moins 50 % en poids bouillent au-dessus de 538 ·C (1000 ·F). Ce catalyseur est tout particulièrement avantageux pour l'hydrocraquage de produits de départ dont 80 % en poids bouillent au-dessus de 538 ·C (1000 ·F).
