摘要
介绍了煤层气超临界吸附的基本特征及近年来煤层气吸附的行为与规律;对影响煤层气吸附的因素以及煤层气吸附模型在研究中所取得的成果进行了总结;分析了煤层气超临界吸附研究中存在的问题,在此基础上,指出煤层气超临界吸附规律、超临界吸附的热力学模型、动力学模型及量子化学模型等将是今后煤层气超临界吸附研究的重点。
Coal adsorbing gas is a basic content of coal bed methane geology, which study have very important theory significance and practical value. Based on the fact that coal bed methane adsorption on coal belong to supercritical adsorption, The paper introduce the essence characteristics of supercritical adsorption between solid and gas two phases, review the theory advances of coal bed methane adsorption from three aspects, the adsorption behaviors and laws of coal bed methane, the influence factors of coal bed methane adsorption and adsorption models of coal bed methane, then discuss the exist problems in the study and prospect the development of coal bed methane adsorption under supercritical condition.
