摘要： The present invention relates to the use, in a method for in-situ activation of at least one hydrotreating, in particular hydrocracking, catalyst, of at least one nitrogen compound having at least one of the following characteristics: a) a nitrogen content by weight in the range from 15 to 35 wt %, relative to the total weight of the nitrogen compound; b) a number of nitrogen atoms in the range from 2 to 20; c) a boiling point in the range from 140° C. to 300° C.; and d) said nitrogen compound being in liquid form at room temperature and atmospheric pressure. The present invention also relates to the method for in-situ activation of at least one hydrotreating catalyst comprising at least one step of sulphiding said hydrotreating catalyst in the presence of a sulphiding agent, and a step of passivation of said hydrotreating catalyst in the presence of said at least one nitrogen compound.

摘要： The invention relates to a device and to a method for continuously measuring the hydrogen sulfide concentration of an off-gas by means of a detachable device suitable for being temporarily connected to equipment producing the off-gas. The method comprises a step of measuring the absorption of electromagnetic radiation by the off-gas. The device and method method can be used in particular to measure the hydrogen sulfide concentration in an off-gas produced during a step of sulfiding a hydroprocessing catalyst.
