摘要(Abstract):
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。结果表明 :在不同频率的交变电磁场作用下 ,煤吸附CO2 、N2 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
Adsorption and desorpion characteristics of methane (CO 2?N 2),from the coal of Zhucun,in alternative electric field with different frequencies have been studied with volumetric method.The result shows that the adsorption property of coal to CO 2,N 2 still coincides with the Langmiur Equation,and the alternative electric field weakens the adsorption ability of coal to methane,decreases the constant b,but does not change the saturated adsorption volume a,being typical surface modification.
