Abstract: Targeting on hydrodesulphurization, hydrodenitrification and hydrodemetallization from inferior VGO, hydrotreating experiments were conducted to investigate the effect of various hydrotreating conditions on the quality of the hydro-products. Meanwhile, variation of the components and its corresponding change of macroscopic properties were also analyzed on the basis of three types of inferior VGO. The rates of hydrodesulfurization, hydrodenitrogenation and hydrodemetallization were improved with the increase of reaction temperature. Compared with raw oil, hydrogenated oil has a low 95% point distillation temperature and density, and the content of sulfur, nitrogen and metal in the produced oil is greatly reduced.

Key words: Hydrotreating, Hydrodesulphurization, Hydrodenitrification, Hydrodemetallization

摘要： 以劣质蜡油加氢脱硫、加氢脱氮、加氢脱金属为目标，对3种不同的劣质蜡油进行了加氢处理实验，研究了加氢处理工艺条件对上述反应过程的影响，并探讨了在不同工艺条件下，加氢生成油的性质及质谱组成变化规律。结果表明，加氢脱硫率、脱氮率、脱金属率均随反应温度升高而增加。与原料油相比，加氢生成油具有较低的95%馏出温度和密度，生成油中硫、氮、金属质量分数大幅度降低。
