The invention relates to a method for impregnating a hydroprocessing metal catalyst in the oxide form with at least one orthophthalate, either dissolved or dispersed in a liquid. The invention further relates to a method for sulphuration of a hydroprocessing metal catalyst in the oxide form, comprising a) an impregnation step as above followed by b) a step for bringing the catalyst treated thus into contact with a sulphuration agent and c) a step for bringing into contact with hydrogen, where step b) is followed by step c) or steps b) and c) are carried out simultaneously.

Procédé d'imprégnation d'un catalyseur métallique d'hydrotraitement sous forme oxyde, avec au moins un orthophtalate éventuellement dissous ou dispersé dans un liquide. Procédé de sulfuration d'un catalyseur métallique d'hydrotraitement sous forme oxyde, comprenant - a) l'étape d'imprégnation selon le dit procédé, suivie de - b) une étape de mise en contact du catalyseur ainsi traité avec un agent de sulfuration, et de - c) une étape de mise en contact avec de l'hydrogène; l'étape b) étant suivie de l'étape c) ou bien les étapes b) et c) étant réalisées simultanément.
