| 摘 要： | 为制备轻质白油，采用贵金属加氢催化剂在30 mL连续加氢实验装置上对煤直接液化柴油进行了深度加氢实验，考察了不同反应压力6～12 MPa，反应温度80～240 ℃，体积空速0.6～1.2 h-1条件下直接液化柴油芳烃饱和行为。研究表明：加氢后的柴油馏程、粘度、密度等性质未有明显变化；但芳烃含量呈现大幅度下降，在合适的加氢条件下产品油中芳烃质量分数可以降低至0.01%以下，满足环保型轻质白油标准。通过蒸馏切割发现，直接液化柴油所生产的轻质白油牌号主要集中在W2-40～W2-110之间。

PREPARATION OF LIGHT WHITE OIL BY HYDROGENATION OF DIESEL FROM DIRECT COAL LIQUEFACTION |
| |
| Abstract: | The eco-friendly light white oil was prepared by hydrogenation of coal direct liquefaction diesel in a 30 mL continuous hydrogenation device using Pd-Pt hydrogenation catalyst at 80～240 ℃,6～12 MPa，LHSV 0.4～1.2 h－1. The results showed that no significant changes in the boiling range, viscosity，density of the diesel oil after hydrogenation was observed. However，the mass fraction of aromatics in the oil is reduced to ＜0.01 % under certain hydrogenation conditions. It was also found that the brand of light white oil produced from direct liquefied diesel is mainly concentrated in the range of WI 40～WI 110. |
