为探究煤的孔径、芳香片层堆砌度、芳香片层延展度、气体温度、气体压力对CH_(4)和Co_(2)竞争吸附的影响,以晋城矿区3号煤为研究对象,对不同温度、压力、孔径、芳香片层堆砌度、芳香片层延展度下煤吸附CH_(4)、Co_(2)二元混合气体的过程进行研究。基于工业分析、X射线衍射试验对煤的微观结构进行测试与分析,采用巨正则系综蒙特卡洛(gCMC)方法对煤吸附混合气体的过程进行分子模拟。结果表明:气体压力增加有利于吸附,压力为5 MPa.,Co_(2)的吸附量已接近饱和;温度增加会导致煤对Co_(2)的最大吸附量和吸附热降低;孔径增大会使煤对CH_(4)的吸附量增大,孔径从1 nm增加到2 nm,CH4的吸附量增加最快;随着芳香片层堆砌度的增加,煤吸附的气体分子数变化不明显,但单位质量煤对Co_(2)的吸附量呈迅速下降趋势,对CH4的吸附量略有降低;随着芳香片层延展度的增加,煤吸附的CH_(4)分子数缓慢增加,吸附的Co_(2)分子数快速增加,单位质量的煤对2种气体的吸附量变化不明显;从吸附量和吸附热2个角度来看,Co_(2)在竞争吸附过程中均处于优势地位,因此向煤层注入Co_(2)可有效驱替CH_(4)。研究结果加强了分子层面对CH_(4)、Co_(2)二元混合气体吸附的认识,可为注Co_(2)强化煤层气开采奠定理论基础。
