Patent ID: 8283278

Claim:
A process for sulfurizing a hydrocarbon treatment catalyst, comprising: at least a first step of depositing, on the surface of the catalyst, one or more sulfurization auxiliaries of formula (I): in which: R 1 denotes a hydrogen atom or a linear or branched, saturated or unsaturated hydrocarbon group comprising from 1 to 30 carbon atoms, R 2 denotes a linear or branched, saturated or unsaturated divalent hydrocarbon-based group comprising from 1 to 8 carbon atoms, and which is substituted with one or more groups selected from the group of —OH, —OR, —NH 2 , —NHR, and —NRR′, wherein R and R′ are alkyl groups comprising from 1 to 4 carbon atoms; R 3 denotes a linear or branched, saturated or unsaturated hydrocarbon group comprising from 1 to 30 carbon atoms; and at least a second step of placing the catalyst in contact with a sulfur-containing gaseous mixture containing hydrogen and a sulfur compound other than the sulfurization auxiliary of formula (I).
