The subject of the present invention is the use, in a process for in-situ activation of at least one hydrotreatment catalyst, in particular hydrocracking, of at least one nitrogen compound having at least one of the following characteristics: a) a nitrogen content by weight ranging from 15 to 35% by weight, relative to the total weight of the nitrogen compound; b) a number of nitrogen atoms ranging from 2 to 20; c) a boiling point ranging from 140 ° C to 300 ° C; and d) said nitrogenous compound being in liquid form at room temperature and at atmospheric pressure. The present invention also relates to the process for activating at least one hydrotreatment catalyst comprising at least one stage of sulfurization of said hydrotreatment catalyst in the presence of a sulfurization agent, and a stage of passivation of said hydrotreatment catalyst. in the presence of said at least one nitrogenous compound. |
