Process for presulphurisation of catalyst for treating hydrocarbons

摘要

Process for sulphurisation, particularly of a refining catalyst containing a support and active metal oxides. In a first stage a sulphur compound based on an organic polysulphide is introduced into the catalytic mass. In a second stage the sulphurisation of the oxides of the active metals is first of all carried out, in the absence of hydrogen, at a temperature below 275 DEG C, and then the activation of the catalyst is carried out in the presence of hydrogen at a temperature above 275 DEG C
