超临界甲烷等温吸附模型对构造煤的适用性研究
Research on Applicability of Supercritical Methane Isothermal Adsorption Model to Tectonic Coal
摘要
Abstract
In order to investigate the applicability of methane isothermal adsorption model to the tectonic coal under supercritical condition,selecting Xutuan Mine as the research area to collect samples,isothermal adsorption experiments were carried out for five samples of the same coal rank under air drying and dry ash free basis.The fitting results of each model is analyzed by the standard deviation.The results show that the models provide a better fitting effect to cracked coal and flake coal,while provide a worse fitting effect to wrinkly and mylonitic coal.The fitting results of D-R-3,D-A-1,D-A-2 and D-A-3 models to the tectonic coal methane supercritical adsorption are more ideal,but the fitting results of B-BET-1,D-R-1,D-R-2 and F models is poor.The pressure range of the model and the processing and calculating method of p° are the important factors which affect the applicability of the model in the super eritical condition.关键词
