Abstract
The present invention concerns a process for “ex situ” treatment of a hydrogenation catalyst containing nickel prior to use, consisting of carrying out three steps, namely bringing the catalyst into contact with at least one sulphur-containing compound or agent (the step termed selectivation), treating said catalyst with hydrogen at a temperature of more than 250° C. (the step termed reduction) and passivation of said catalyst.
