CA 2659797

Described is a catalyst and process useful in the hydrodesulfurization of a distillate feedstock to manufacture a low-sulfur distillate product. The catalyst comprises a calcined mixture of inorganic oxide material, a high concentration of a molybdenum component, and a high concentration of a Group VIII metal component. The mixture that is calcined to form the calcined mixture comprises molybdenum trioxide, a Group VIII metal compound, and an inorganic oxide material. The catalyst is made by mixing the aforementioned starting materials and forming therefrom an agglomerate that is calcined to yield the calcined mixture that may be used as the catalyst or catalyst precursor.

L'invention concerne un catalyseur et un procédé utiles dans l'hydrodésulfuration d'une charge d'alimentation de distillat pour fabriquer un distillat à faible teneur en soufre comme produit. Le catalyseur comprend un mélange calciné d'une matière d'oxyde inorganique, une concentration élevée d'un composant au molybdène, et une concentration élevée d'un composant d'un métal du Groupe VIII. Le mélange qui est calciné pour former le mélange calciné comprend le trioxyde de molybdène, un composé de métal du Groupe VIII et une matière d'oxyde inorganique. Le catalyseur est obtenu par mélange des matières de départ mentionnées ci-dessus et par formation à partir de celles-ci d'un agglomérat qui est calciné pour produire le mélange calciné qui peut être utilisé comme catalyseur ou précurseur de catalyseur.
