Abstract
A process for producing a gas oil fraction by hydrodesulfurizing a feedstock oil prepared by blending a straight-run gas oil and a light cycle oil, wherein the process is capable of maintaining the activity of the desulfurization catalyst over a long period, and is capable of producing a low-sulfur gas oil fraction having a low sulfur content and excellent color index. The process for producing a low-sulfur gas oil fraction includes hydrodesulfurizing a feedstock oil to a sulfur content of not more than 10 ppm by mass, wherein the feedstock oil is prepared by blending a straight-run gas oil with a light cycle oil having a 10 volume % distillation temperature of less than 220° C. and a 90 volume % distillation temperature of less than 325° C., such that the blend proportion of the light cycle oil is not more than 30% by volume. Further, a low-sulfur gas oil is obtained by blending the low-sulfur gas oil fraction with a kerosene fraction.
