Chinese. [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1.2～2.0 nm范围内的孔容积越大，活性炭丁烷活性越大；0.5～0.9 nm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。

[Method] Eight activated carbons were 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).
