[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。

[Objective] The paper was to study the effect of microporous structure of ac- tivated carbon on adsorption performance of n-butane. [Method] Using 8 activated car- bons prepared from different materials and technologies, the effects of physical prop- erties of activated carbon on butane adsorption performance were investigated. [Result] Specific surface area, pore volume and pore size distribution of activated carbon exert- ed remarkable effects on butane adsorption. The activated carbon with high percent- age 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.
