| 摘 要： | 采用浸渍法将金属负载到活性炭纤维(ACF)上对其进行改性,研究了负载金属改性ACF对模型油(二苯并噻吩-正辛烷)的吸附脱硫效果,对比了不同单金属和复合金属盐改性ACF的脱硫性能。实验结果表明:Ag和Zn复合改性的ACF具有最好的脱硫性能;在吸附温度为40℃,吸附时间为2.5 h,油剂质量比为21.5的优化条件下,脱硫率高达97.55%,且具有良好的重复利用性。

| Abstract: | The activated carbon fiber （ACF）was modified with supported metal by impregnation method,and its desulfurization effect by adsorption to model oil （dibenzothiophene-n-octane）was studied. The desulfurization capabilities of ACF modified by different single and composite metal salt were compared. The experimental results showed that：The ACF modified by both Ag and Zn had the best desulfurization capability;Under the optimized conditions of adsorption temperature 40 ℃,adsorption time 2.5 h and mass ratio of oil to adsorbent 21.5,the desulfurization rate on the modified ACF was up to 97.55%,and it had good reuse performance. |
