The instant invention is directed to the preparation of a catalyst composition suitable for the hydroconversion of heavy oils. The catalyst composition is prepared by a series of steps, involving mixing a group VIB metal oxide and aqueous ammonia to form an aqueous mixture, and sulfiding the mixture to form a slurry. The slurry is then promoted with a Group VIII metal. Subsequent steps involve mixing the slurry with a hydrocarbon oil and combining the resulting mixture with hydrogen gas and a second hydrocarbon oil having a lower viscosity than the first oil. An active catalyst composition is thereby formed.

L'invention concerne la préparation d'une composition catalytique permettant l'hydroconversion d'huiles lourdes. Cette composition catalytique est préparée par la mise en oeuvre d'une série d'étapes comprenant le mélange d'un oxyde métallique du Groupe VIB et d'ammoniac aqueux pour former un mélange aqueux, et la sulfuration de ce mélange pour former une suspension épaisse. Ladite suspension est ensuite promue au moyen d'un métal du Groupe VIII. Des étapes ultérieures comprennent le mélange de la suspension épaisse à une huile hydrocarbonée, et l'association du mélange résultant à un gaz hydrogène et à une deuxième huile hydrocarbonée présentant une viscosité inférieure à celle de la première huile, ce qui permet d'obtenir une composition catalytique active.
