摘要
用容量法对焦作朱村矿变质无烟煤在不同频率的交变电磁场中吸附解吸特征进行了研究。实验结果表明:不同频率的交变电磁场作用下,煤吸附CO_2、N_2仍旧符合Langmiur方程;交变电磁场减弱了煤的吸附能力,减小了吸附常数b值,但饱和吸附量(a值)基本上不变,是典型的表面改性现象,并从量的角度分析其改性的程度。
Adsorption and desorpion characteristics of methane (CO2,N2) in Zhucun coal mine of Jiaozuo in alternative electric field with different frequencies have been studied by the method of volume. The result shows absorption property of coal to CO2,N2 still accords with the Langmiur Equation; The alternative electric field weakens the absorption ability of coal to methane , decreases the constant b; and does not change the saturated absorption volume a; it is typical surface modification, and the extent of modification is analyzed quantitatively.
