摘要
矿井瓦斯中CH4与N2和CO2的有效分离是解决低浓度瓦斯回收利用的技术关键.为此,利用自制的吸附装置,研究了CH4、N2、CO2及其两相混合物在沥青基碳纤维分子筛(ACF-MS)上的吸附、分离特征.结果表明,单组分吸附时,ACF-MS对CO2具有较高的吸附量,CH4次之,N2最低.1:1mol两相混合气体吸附时,ACF-MS对CO2/N2有较好的吸附分离作用,对CH4/N2和CH4/CO2的分离效果较差.
The effective separation between CH4 and N2, and CO2 in the mine gas is a key technology for low-concentration gas recovery and utilization. For this purpose, the adsorption and separation characteristics of the CH4, N2, CO2, and their two-phase mixtures are studied on the pitch-based activated carbon fiber molecular sieve （ACF-MS）, using the absorption-made device. The results show that for single-component adsorption, ACF-MS have a higher CO2 adsorption, CH4 times, N2 minimum. For two-phase mixed gas with the 1：1 mol mixture ratio, ACF-MS has a better effect on the adsorption separation of CO2 and N2, and the separation of CH4 and CO2. and CH4 and N2 are less effective.
