通过以煤样为吸附剂的CO_2置换CH_4模拟实验,发现了自然条件下和煤层气开采条件下的煤层气置换解吸现象,并借助于现代物理化学和界面化学的吸附理论,深入探讨了煤层气的竞争吸附与置换解吸机理,为深入研究煤层气开采过程中的煤层气解吸机理探索了一条新的途径．
Through coal-based sorbent CO_2 displacement CH_4 simulation experiments, we found the CBM gas desorption and desorption under natural conditions and coalbed methane extraction conditions, and with the aid of modern physical chemistry and interface chemistry adsorption theory, in-depth discussion of the CBM The competitive adsorption and displacement desorption mechanism have explored a new approach for the further study on the desorption mechanism of coalbed methane during the process of coalbed methane exploitation.
