摘要:
运用Langmuir单分子层吸附理论,分析了煤对甲烷吸附能力受其含水量的影响。利用WY-98B型瓦斯常数测定仪,分别对2种煤样在不同含水量时吸附甲烷气体的等温吸附曲线、Langmuir压力、吸附常数a,b进行了定性与定量分析,得出了煤对甲烷吸附量随压力的变化关系式及Langmuir吸附常数a,b随煤样内水含量变化的关系式。研究结果表明:含水煤样依然满足Langmuir单分子层吸附理论,吸附常数a,b与煤样中含水量的变化之间存在着一定相关性。
Abstract:
Adopting the Langmuir monolayer theory for methane adsorption of coal, the effects of moisture to methane adsorption of coal was studied. Using the WY-98B-type gas constant detector to analyze the curve of isothermal adsorption, Langmuir pressure and adsorption constants a and b of two coal samples with qualitative and quantitative at different moistures. The equation for pressure effects on adsorption quantity was gained and the equation for moisture effects on adsorption constants a and b was gained too. The result of experiment shows that containing moisture coal sample fit the Langmuir adsorption equation and adsorption constants a and b and change of water content in coal samples have correlation.
