| 摘 要： | 煤吸附甲烷量一般用Langmuir方程来表示 .Langmuir方程是用单分子层吸附模型推导出来的 ;在理论上 ,煤吸附甲烷不符合单分子层吸附模型 .由于煤吸附甲烷得到的吸附等温线都属于第Ⅰ类吸附等温线 ,所以可以用Langmuir方程来表示煤吸附甲烷量 ;同时 ,Langmuir方程使用方便 ,两个吸附常数a和b的物理意义明确 ,因而应用广泛

| Abstract: | Langmuir equation is commonly used to study methane adsorption by coal.Generally,Langmuir equation is based on the adsorption model of monomolecular layer.Theoretically,methane adsorption by coal doesn′t conform to adsorption model of monomolecular layer.Both adsorption models of monomolecular layer and methane adsorption by coal are described by Type*!Ⅰ*!adsorption isotherm.Practically,Langmuir equation can be used to study methane adsorption by coal.Furthermore,Langmuir equation is widely used due to its convenience for the using and the meaningful adsorption constants about a and b. |
