<p>The present invention pertains to a process for sulphiding a catalyst composition comprising at least one hydrogenation metal component of Group VI and/or Group VIII of the Periodic Table, and an S-containing organic additive wherein the catalyst composition is contacted with hydrogen and a sulphur-containing compound in the gaseous phase, characterised in that the process is carried out ex situ. By carrying out the process ex situ, the formation of undesirable side compounds in the hydrotreating unit is prevented. Additionally, the reactor suffers less downtime, and the start-up of the reactor may be simplified. The S-containing organic additive preferably is a mercapto-compound, more preferably a mercaptocarboxylic acid represented by the general formula HS-R1-COOR, wherein R1 stands for a divalent hydrocarbon group with 1-10 carbon atoms and R stands for a hydrogen atom, an alkali metal, an alkaline earth metal, ammonium, or a linear or branched alkyl group having 1 to 10 carbon atoms.</p> |
