Abstract:
1. A method for producing a low sulfur diesel product, comprising: introducing a feedstock containing both a mineral portion and from about 0.1 wt % to about 50 wt % of a biocomponent portion, the mineral portion having an initial boiling point of at least 550° F.; hydrotreating the feedstock in a first reaction zone under first effective hydrotreating conditions including an LHSV of 0.3 to 2.0, a total pressure from about 1400 to about 3000 psig, a treat gas rate of at least about 2000 scf/b of at least 80% hydrogen, and a temperature of from about 650-800° F., to produce a hydroprocessed feedstock having a sulfur content of about 100 wppm S to about 1500 wppm S; fractionating the hydroprocessed feedstock to produce a diesel boiling range fraction and a portion boiling higher than the diesel range; hydrotreating the diesel boiling range fraction in a second reaction zone under second effective hydrotreating conditions including an LHSV of 0.5 to 1.5, a total pressure from about 250 to about 800 psig, and a temperature of from about 550-750° F. to produce a diesel boiling range product.
