Abstract

The present invention relates to a sulphiding agent for a hydrotreating catalyst which makes possible faster sulphiding of the catalyst but which also makes possible to very significantly limit solid deposits, in particular of sulphur. The sulphiding agent according to the invention is essentially composed of diethyl disulphide (DEDS) or dipropyl disulphide(s) (DPDS) or dibutyl disulphide(s) (DBDS) and can be employed in 'in situ' and 'ex situ' presulphidation processes.
