Multi-metallic bulk catalysts and methods for synthesizing the same are provided. The multi-metallic bulk catalysts contain nickel, molybdenum tungsten, yttrium, and optionally, copper, titanium and/or niobium. The catalysts are useful for hydroprocessing, particularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feedstocks. L'invention concerne des catalyseurs en vrac multi-métalliques et des procédés de synthèse de ceux-ci. Les catalyseurs en vrac multi-métalliques contiennent du nickel, du molybdène tungstène, de l'yttrium et éventuellement du cuivre, du titane et/ou du niobium. Les catalyseurs sont utiles pour l'hydrotraitement, en particulier l'hydrodésulfuration et l'hydrodénitrogénation, de charges d'hydrocarbures.
