Abstract
The present invention concerns a process for sulphurising a hydrocarbon hydrotreatment catalyst in the presence of hydrogen and at least one sulphur-containing compound. The process is characterized in that the catalyst comprises a carbon-containing compound the major portion of which is not leachable deposited in its pores. The invention is of particular application to sulphurization carried out off-site.
