摘要
用LI吸附-流动曲面方程可以定量衡量温度和压力对煤层气在煤层中的吸附和流动的共同影响。LI吸附-流动方程形式简单,计算方便,并可将结果作成三维视图。Freundlich等温吸附方程处理吸附数据,每个测试温度就会有一个参数β。而LI吸附-流动方程是用于回归所有测定温度、压力和被测吸附介质的性能对煤层气吸附的影响。所以一个煤样,只有一个参数β。对于本文所选择的数据,同样以Langmuir方程计算的吸附"兰氏计算值"为基准,吸附"李氏计算值"的相对误差是相当于吸附"弗氏计算值"的相对误差。
LI adsorption- flow equation can be used as a quantitative measure of the combined effects of both temperature and pressure on coal- bed methane adsorption. LI adsorption- flow equation is simple,convenient and results can be illustrated into a three dimensional view. Freundlich isothermal adsorption,for one coal sample,each of the test temperatures has a parameter β. And LI adsorption- flow equation,for one coal sample,has only one parameter β for all testing temperatures. Based on the same ＂measured＂data,which is calculated from published set of Langmuir parameters,the relative average error produced from LI adsorption- flow equation is equivalent to the relative average error produced from Freundlich adsorption isotherm equation.
