Processes for producing diesel fuel having sulfur content of 10 ppm by weight or less from feed sources including up to 20% by weight of a biocomponent feedstock. The process includes hydrotreating the feed sources in a first reaction zone under hydrotreating conditions, separating the first hydrotreated stream effluent from gas components and hydrotreating the first hydrotreated stream effluent in a second reaction zone under hydrotreating conditions. The mineral hydrocarbon of the feed sources can be distillate or heavier feed sources.

L'invention porte sur des procédés pour la fabrication d'un carburant diesel présentant une teneur en soufre inférieure ou égale à 10 ppm en poids à partir de sources d'alimentation contenant jusqu'à 20 % en poids d'une charge de départ à bioconstituant. Le procédé comprend l'hydrotraitement des sources d'alimentation dans une première zone de réaction dans des conditions d'hydrotraitement, la séparation du premier effluent de courant hydrotraité à partir de constituants gazeux et l'hydrotraitement du premier effluent de courant hydrotraité dans une seconde zone de réaction dans des conditions d'hydrotraitement. L'hydrocarbure minéral des sources d'alimentation peut être un distillat ou des sources d'alimentation plus lourdes.
