摘　　要：以常二线柴油、常三线柴油、减一线柴油、催化柴油、焦化柴油、渣油加氢柴油的混合物为原料(六者质量分数依次为14.49%,5.58%,3.25%,34.45%,25.05%,17.18%),在小型加氢装置中进行了加氢脱硫反应。结果表明:在相同条件下,比表面积和孔容为最高的HPL-1催化剂加氢脱硫效果最好;在反应温度为360℃,反应压力为7.0 MPa,体积空速为0.8 h-1,氢气/原料油(体积比)为800的最佳反应条件下,产物中硫含量约为11μg/g,脱硫率达到98.67%。The hydrodesulfurization was carried out in a small- scale hydrogenation unit with the atmospheric diesel oil 2#,3#and vacuum diesel oil 1#,catalytic diesel oil,coker diesel,residue hydrocracking diesel as raw materials,and the mass fraction of them was 14. 49%,5. 58%,3. 25%,34. 45%,25. 05%,17. 18% respectively. The results showed that under the same conditions,HPL- 1 catalyst with the highest superficial area and pore volume had the best effect of hydrodesulfurization. The sulphur content in the product was about 11 μg / g,and the rate of desulfurization reached 98. 67% under the optimum conditions of reaction temperature 360 ℃,reaction pressure 7. 0 MPa,volume space velocity0. 8 h- 1,hydrogen /oil（ volume ratio） 800.
