Described is a catalyst useful in the hydroprocessing of a heavy hydrocarbon feedstock wherein the catalyst comprises a calcined mixture made by calcining a formed particle of a mixture comprising molybdenum trioxide, a nickel compound, and an inorganic oxide material. The catalyst may be made by mixing an inorganic oxide material, molybdenum trioxide, and a nickel compound to form a mixture that is formed into a particle and calcined to provide a calcined mixture. The process involves the hydrodesulfurization and hydroconversion of a heavy hydrocarbon feedstock which process may include the conversion of a portion of the pitch content of the heavy hydrocarbon feedstock and the yielding of a treated product having an enhanced stability as reflected by its P-value.
L'invention concerne un catalyseur utile dans l'hydrotraitement d'une charge d'alimentation en hydrocarbures lourds, le catalyseur comprenant un mélange calciné obtenu par la calcination de particules formées d'un mélange comprenant du trioxyde de molybdène, un composé de nickel et une matière d'oxyde inorganique. Le catalyseur peut être obtenu par mélange d'une matière d'oxyde inorganique, du trioxyde de molybdène et d'un composé de nickel pour former un mélange qui est transformé en particules et calciné pour fournir un mélange calciné. Le procédé met en jeu l'hydrodésulfuration et l'hydroconversion d'une charge d'alimentation en hydrocarbures lourds, lequel procédé peut comprendre la conversion d'une fraction de la teneur en brai de la charge d'alimentation en hydrocarbures lourds et la production d'un produit traité ayant une stabilité augmentée telle que reflétée par sa valeur P.
