The present invention provides methods of synthesizing molybdenum disulfide (MoS2) and carbon-containing molybdenum disulfide (MoS2-XCX) catalysts that exhibit improved catalytic activity for hydrotreating reactions involving hydrodesulfurization, hydrodenitrogenation, and hydrogenation. The present invention also concerns the resulting catalysts. Furthermore, the invention concerns the promotion of these catalysts with Co, Ni, Fe, and/or Ru sulfides to create catalysts with greater activity, for hydrotreating reactions, than conventional catalysts such as cobalt molybdate on alumina support.

La présente invention concerne des méthodes de synthèse de catalyseurs de disulfure de molybdène (MoS¿2?) et de disulfure de molybdène à base de carbone (MoS¿2-X?C<SB>X</SB>) présentant une activité catalytique améliorée pour des réactions d'hydrotraitement impliquant une hydrodésulfuration, une hydrodénitrogénation et une hydrogénation. L'invention concerne également les catalyseurs ainsi obtenus, ainsi que l'activation de ces catalyseurs avec des sulfures de Co, Ni, Fe et/ou Ru, en vue de produire, pour des réactions d'hydrotraitement, des catalyseurs dont l'activité est supérieure à celle de catalyseurs classiques, tels que les catalyseurs à molybdate de cobalt sur support d'alumine.
