[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 research aimed to study the influence of activated carbon micropore structure on butane adsorption. [Method] Eight activated carbons with different raw materials and different processes were selected to study the influence of micropore of activated carbon on the adsorption performance of butane by measuring the physical properties of activated carbon. [Result] The specific surface area, pore volume and pore distribution of activated carbon samples were closely related to butane adsorption. The larger the pore volume in the range of 1.2-2.0 nm in the micropore is, the larger the butane activity of the activated carbon is. The larger the pore volume of 0.5-0.9 nm is, the larger the butane adhesion of the activated carbon is and the smaller the BWC is. [Conclusion] The study provided a reference for the adsorption of activated carbon.
