| 摘 要： | 目的]研究活性炭微孔结构对丁烷吸附的影响。方法]选用8个不同原料、不同工艺生产的活性炭,通过测定活性炭物理性能,研究了活性炭的微孔对丁烷吸附性能的影响。结果]活性炭样品的比表面积、孔容积和孔分布与丁烷吸附有着密切的关系。微孔中的1.2～2.0nm 范围内的孔容积越大,活性炭丁烷活性越大;0.5～0.9nm的孔容积越大,活性炭丁烷持附性越大,导致BWC会越小。结论]为活性炭的吸附研究提供参考。

| Abstract: | Objective] The paper was to study the effect of microporous structure of activated carbon on adsorption performance of n-butane.Method] Using 8 activated carbons prepared from different materials and technologies,the effects of physical properties of activated carbon on butane adsorption performance were investigated.Result] Specific surface area,pore volume and pore size distribution of activated carbon exerted remarkable effects on butane adsorption.The activated carbon with high percentage of micropore volume within the range of 1.2-2 nm possessed high butane activity.The level of butane retentivity rose with the increase of the volume of pore within the range of 0.5-0.9 nm,which led to smaller butan working capacity(BWC).Conclusion] The study provided reference for the adsorption research for activated carbon. |
