【摘要】：為了更準(zhǔn)確地描述煤體對甲烷的吸附特性,基于常規(guī)等溫吸附試驗(yàn),對煤體甲烷吸附量進(jìn)行了修正,引入了真實(shí)吸附量和視吸附量的計(jì)算方法,對比分析了視吸附量和真實(shí)吸附量之間的差異以及溫度對二者差異性的影響;并以真實(shí)吸附量為基礎(chǔ),得到飽和吸附量和溫度間的函數(shù)關(guān)系。結(jié)果表明:真實(shí)吸附量和視吸附量之間的差異會隨著溫度升高而逐漸顯著,90℃時,二者差異最大,可達(dá)8%;煤體的吸附能力與其比表面積成正比,隨著溫度升高,因煤體比表面積不斷增大,飽和吸附量隨溫度呈線性規(guī)律增長。研究結(jié)果可為正確認(rèn)識煤體對煤層氣的吸附特性及煤層氣資源的開發(fā)利用提供參考。
[Abstract]:In order to describe the adsorption characteristics of methane on coal body more accurately, based on the conventional isothermal adsorption test, the adsorption capacity of methane in coal body was modified, and the calculation method of real adsorption capacity and apparent adsorption capacity was introduced. The difference between apparent adsorption capacity and real adsorption capacity and the effect of temperature on their differences were analyzed, and the functional relationship between saturation adsorption capacity and temperature was obtained based on the real adsorption capacity. The results show that the difference between the real adsorption capacity and apparent adsorption capacity will become more and more significant at 90 鈩，
