Supported metallic catalysts comprised of a Group VIII metal, a Group VIB metal, and an organic additive, and methods for synthesizing supported metallic catalysts are provided. The catalysts are prepared by a method wherein precursors of both metals are mixed and interacted with at least one organic additive, dried, calcined, and sulfided. The catalysts are used for hydroprocessing, particularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feedstocks.
L'invention concerne des catalyseurs métalliques supportés constitués d'un métal du groupe VI, d'un métal du groupe VIB et d'un additif organique, et des procédés destinés à synthétiser des catalyseurs métalliques supportés. On prépare les catalyseurs à l'aide d'un procédé qui consiste à mélanger les précurseurs des deux métaux et à les faire interagir avec au moins un additif organique séché, calciné et sulfuré. On utilise les catalyseurs pour l'hydrocraquage, en particulier pour l'hydrodésulfuration et l'hydrodésazotation, de charges d'hydrocarbures.
