| 摘 要： | 对炭化玉米秆、炭化油菜杆和炭化竹子杆对柴油的吸附性能进行了试验研究．试验发现，3种植物炭材料都具有一定的吸油能力，其中炭化玉米秆吸油性能最佳．用扫描电镜、压汞和N2吸附方法，检测了3种植物炭材料的孔径大小、分布和比表面积．中大孔径（500-7500nm）的植物炭材料改善了毛细作用，对柴油的吸附性能较好．吸油率与比表面积之间没有明显的相关性．对于液相吸附，比表面积的影响可以忽略． |

| Abstract: | Diesel oil sorption behaviours were investigated experimentally on three kinds of plant charcoals including carbonized corn,cole and bamboo stalks.All the materials under investigation show some ability of diesel oil sorption,with the carbonized corn stalks being the best.Scanning electron microscope(SEM) analysis,mercury porosimetry and nitrogen adsorption were conducted to measure the sizes and distributions of pores and specific areas of the three plant charcoals.The results show that the plant charcoals with large pores(500 to 7 500 nm) have good diesel oil asorption ability because of good capillarity.There is no obvious relationship between diesel oil sorption behaviours and specific area,the effect of which is nelegible in terms of liquid adsorption. |
| Keywords: | diesel oil plant charcoal oil sorption materials capillary sorption behaviour |
