| 摘 要： | 对河北开滦矿区不同变质程度的煤进行了纯CO2和纯CH4气体等温吸附实验，并用Langmuir模型、三参数BET模型和吸附势理论模型（DR，DA）对煤的吸附实验数据进行了拟合，检验了各模型的拟合程度。结果表明：中煤阶烟煤的马家沟矿9号煤（Ro, ran = 1.21%）对CH4和CO2吸附能力比低煤阶烟煤的林南仓矿11号煤（Ro, ran = 0.58%）的吸附能力大；在相同压力下，同一煤样对CO2的吸附能力明显大于对CH4的吸附能力。马家沟矿9号煤对CO2和CH4的等温吸附线具有典型的I型特征，各模型对其吸附行为拟合误差相差很小，可用Langmuir方程描述；林南仓矿煤等温吸附线较复杂，因用Langmuir描述误差较大，应优先选择误差较小的吸附势理论DA模型来描述其吸附行为。9号煤对CH4和11号煤对CO2和CH4的吸附均以单分子层吸附为主。 |

| Abstract: | Isothermal adsorption experiments of pure CO2 and CH4 on different coals in rank (the No.11 Coal from the Linnancang Mine and the No.9 Coal from the Majiagou Mine) from the Kailuan Coalfield of Hebei Province, China, have been studied. Four different models (Langmuir, BET, D-R, and D-A) were used to fit the experimental data of CO2 and CH4 adsorption and their fitting degree were investigated. The results showed that the adsorption capacity of the Majiagou coal(Ro, ran=1.21%)is higher than that of the Linna... |
