The present invention relates to a sulphidation agent for a hydroprocessing catalyst that provides a faster sulphidation of the catalyst and also significantly reduces solid deposits, essentially sulphur. The sulphidation agent of the present invention essentially consists of diethyldisulphide (DEDS) or dipropyldisulphide(s) (DPDS) or dibutyldisulphide(s) (DBDS), and can be used in in-situ or ex-situ presulphidation methods.
La présente invention concerne un agent de sulfuration pour catalyseur d'hydro traitement qui permet une sulfuration plus rapide du catalyseur mais aussi de limiter très significativement les dépôts solides, notamment de soufre. L'agent de sulfuration selon l'invention consiste essentiellement en diéthyldisulfure (DEDS) ou dipropyldisulfure(s) (DPDS) ou dibutyldisulfure(s) (DBDS) et peut être mis en AEuvre dans des procédés de présulfuration "in-situ" et "ex-situ".
