| 摘 要： | 采用理想狭缝孔模型，微孔容积填充理论和分段吸附机理，用Langmuir公式计算活性炭纤维理想的甲烷吸附等温线，并通过与实测结果的比较分析，对Langmuir公式进行了修正，引入与微孔孔径分布有关的修正系数k，研究结果表明：相对于孔径小于1nm的微孔，活性炭纤维1－2nm微孔对吸附量影响较大，用修正公式计算的结果与实测数据吻合较好。

| Abstract: | The methane adsorption isotherm of the activated carbon fibers was calculated using Langmuir formula,which was based on the idealized slit model and micro pore filling mechanism,as well as step by step adsorption theory.By analyzing and comparing the calculation and the experimental results,the Langmuir formula is modified,and a coefficient k is introduced where k is related to the distribution of the pore size.The results show that the micro pores with sizes of 1-2 nm have bigger influences on the methane adsorption than that with the sizes of less than 1 nm do .The calculation results are found to fit the experimental data well. |
