摘要：
The process for desulfurizing a gas oil fraction according to the invention comprises a low-boiling gas oil fraction hydrodesulfurization step (I) wherein a low-boiling gas oil fraction is desulsurized under the condition of a H2/Oil ratio of 70 to 200 Nm3/kl to obtain a treated oil, a high-boiling gas oil fraction hydrodesulfurization step (II) wherein a high-boiling gas oil fraction is desulsurized under the condition of a H2Oil ratio of 200 to 800 Nm3/kl to obtain a treated oil, and a step (III) wherein the treated oil obtained in the step (I) is mixed with the treated oil obtained in the step (II), and in this process, at least a part of a gas containing unreacted hydrogen in the step (II) is used for the hydrodesulfurization of the step (I).
