摘 要:
我国煤层气资源非常丰富，储量居世界第三位。其主要成分是甲烷，但煤层气中甲烷气体利用率却较低。主要原因是煤层气的分离提纯工作比较困难。对于吸附分离的工艺而言，关键是甲烷气体吸附剂的选择和制备。本文回顾了吸附分离技术的概况以及甲烷气体吸附剂的发展进程。鉴于膨润土资源深加工利用的良好前景以及岩石、煤等矿物吸附甲烷研究的现状，笔者提出对改性膨润土作为甲烷气体吸附剂的可能性进行探讨，并认为从理论和经济方面都是可行的。[著者文摘]

Abstract:
Coal-bed gas resource in china is very abundant and gas reserves is the third of world. Its main composition is methane, but the utilization of methane is low. The main reason is that it is very difficult. For PSA, the key is the choice and preparation of methane adsorbent. This paper looked back general situation of technology of adsorption and separation and the development progresses of methane adsorbent. As for the prospect of further manufacture of bentonite resource and the present situation of study on mineral substance such as rock and coal adsorbing methane, author firstly discussed the possibility to modify bentonite as the methane adsorbent and thought that it is feasible.[著者文摘]
