CA 2747862

Processes are provided for producing a diesel fuel product having a sulfur content of 10 ppm by weight or less from feed sources that include up to 50% by weight of a biocomponent feedstock. The biocomponent feedstock is co-processed with a heavy oil feed in a severe hydro treating stage. The product from the severe hydrotreatment stage is fractionated to separate out a diesel boiling range fraction, which is then separately hydrotreated.

L'invention concerne des procédés de production d'un produit de carburant diesel, dont la teneur en soufre est inférieure ou égale à 10 ppm en poids, à partir de sources d'alimentation contenant jusqu'à 50 % en poids d'une charge de biocomposants. La charge de biocomposants est co-traitée avec une charge d'huile lourde dans une étape d'hydrotraitement drastique. Le produit obtenu après l'étape d'hydrotraitement drastique est fractionné pour séparer une fraction dont le point d'ébullition se trouve dans la plage d'ébullition du diesel, laquelle est ensuite hydrotraitée séparément.
