Abstract:
1. A method for processing a crude oil, comprising: separating a crude oil feedstock to form at least a naphtha fraction and a heavier crude oil fraction, a first cut point temperature for separating a lighter crude oil fraction comprising the naphtha fraction from the heavier crude oil fraction being a temperature from about 250° F. (121° C.) to about 400° F. (204° C.), the heavier crude oil fraction including a portion having a boiling point greater than 1050° F. (566° C.); hydrotreating the naphtha fraction under effective naphtha hydrotreating conditions to form a hydrotreated naphtha effluent; exposing the heavier crude oil fraction to a hydroconversion catalyst under effective hydroconversion conditions to form a hydroconverted effluent, the effective hydroconversion conditions being effective for conversion of at least about 30 wt % of the portion of the heavier crude oil having a boiling point greater than 1050° F. (566° C.); separating the hydroconverted effluent to form at least a distillate fraction and a bottoms fraction, a second cut point temperature for separating the distillate fraction from the bottoms fraction being a temperature from about 650° F. (343° C.) to about 800° F. (427° C.); and hydrotreating the distillate fraction under effective hydrotreating conditions to form a hydrotreated distillate effluent.
