Claim Text:
1. A method for producing a low sulfur diesel product, comprising: hydroprocessing a mineral feedstock having a T5 boiling point of at least about 600° F. (about 315° C.) in a first reaction zone under first effective hydroprocessing conditions to cause conversion of at least a portion of the mineral feedstock to diesel boiling range compounds; fractionating the hydroprocessed feedstock to produce a diesel boiling range fraction and a portion having a higher boiling range than the diesel boiling range fraction; mixing the diesel boiling range fraction with a biocomponent feedstock in an ebullating bed reactor, the biocomponent feedstock being introduced above a catalyst support grid; hydrotreating the mixed feedstock in the ebullating bed reactor under second effective hydrotreating conditions; and hydrotreating the liquid effluent from the ebullating bed reactor in a supplemental reactor under third effective hydrotreating conditions to make a diesel boiling range product having a desired sulfur content specification.
