摘要
利用ASAP2020比表面积分析仪研究了阳泉煤在液氮浴(77K)条件下对N2吸附特性,根据该温度下的吸附等温线确定出ε-ω吸附特性曲线,同时根据Langmuir单分子层吸附模型和BET多分子层吸附模型得出了完全相同的ε-ω吸附特性曲线,表明ε-ω吸附特性曲线与煤对N2吸附的吸附模型无关。因此可以根据ε-ω吸附特性曲线确定不同温度下的吸附等温线。
Application of ASAP2020 instrument,adsorption charactereristics of nitrogen on YangQuan coal samples were studied at temperature of 77K. The ε - ω adsorption characteristics curve is confirmed by the adsorption isotherm under that temperature. Ulteriorty, the some ε - ω adsorption characteristics curve is obtained by both Langmuir monolayer adsorption model and BET multilayer adsorption model. It shows that ε - ω adsorption characteristics curve is independent of the adsorption model. So bases on ε - ω adsorption characteristics curve,we can confirm different temperiture＇s adsorption isotherm.
