A process for the sulfiding of a hydrodesulfurization catalyst for example in a distillation column reactor. The catalyst in the distillation column reactor is first dried using nitrogen and the reactor is filled with a sulfiding solvent and circulation begun. The reactor is heated to a temperature above the decomposition temperature of the sulfiding agent to be used and the sulfiding agent charged to the reactor. When sulfiding agent breakthrough is noted in the overheads the temperature is raised and held until sulfiding is complete.

L'invention concerne un procédé de sulfuration d'un catalyseur d'hydrodésulfuration, par exemple, dans un réacteur à colonne de distillation. Ledit catalyseur est d'abord séché à l'aide d'azote, le réacteur est rempli d'un solvant de sulfuration, et la circulation commence. Ledit réacteur est ensuite chauffé à une température supérieure à la température de décomposition de l'agent de sulfuration utilisé, et cet agent est chargé dans le réacteur. Lorsqu'on remarque une percée de l'agent de sulfuration dans des produits de tête, la température est élevée et maintenue jusqu'à exécution de la sulfuration.
