Abstract The deep desulfurization process of a diesel oil hydrocarbonated cut having distillation interval of 150-450[deg] C and nitrogen compounds of greater than 100 ppmN, comprises hydrodesulfurization of nitrogen compounds present in an adsorption unit, and regenerating nitrogen compounds using captation masses by desorbing a part of the desulfurized gas effluent obtained from the hydrodesulfurization. A sulfur content in a diesel oil effluent is greater than 3 ppmS. Adsorbing masses used in the adsorption unit consist of faujasite type zeolites. The deep desulfurization process of a diesel oil hydrocarbonated cut having distillation interval of 150-450[deg] C and nitrogen compounds of greater than 100 ppmN, comprises hydrodesulfurization of nitrogen compounds present in an adsorption unit, and regenerating nitrogen compounds using captation masses by desorbing a part of the desulfurized gas effluent obtained from the hydrodesulfurization. A sulfur content in a diesel oil effluent is greater than 3 ppmS. Adsorbing masses used in the adsorption unit consist of faujasite type zeolites having a ratio of silicon/aluminum greater than 1. The water content of the diesel oil is deduced at 150-170[deg] C in a treatment series after hydrodesulfurization. A cycle time of a reactor functioning in the adsorption unit is greater than 20 hours. L'invention décrit un procédé amélioré de désulfuration profonde d'une coupe hydrocarbonée de type gazole comprenant une unité d'hydrodésulfuration catalytique précédée d'une unité d'adsorption des composés azotés inhibiteurs de la réaction d'hydrodésulfuration.
