Catalysts for the treatment of hydrocarbons are presulfurized or presulfided ex-situ, in the absence of hydrogen, by means of a polysulfide of the general formula R--S.sub.(n) --R' wherein n is an interger from 3 to 20 and R and R' are each an organic radical having from 1 to 150 carbon atoms, R' being optionally a hydrogen atom, the so-presulfurized or presulfided catalysts being subsequently activated with hydrogen during their use in the hydrotreatment process of a hydrocarbon charge, i.e. in-situ. An aldehyde or an alcohol or a ketone, an ether or an organic acid, may be added, as promoter, to the polysulfide.
