摘　　要：针对甲烷气体(煤矿乏风瓦斯)的富集与分离,研究了活性炭吸附材料(AC)的Ti改性方法,讨论了对CH4/N2分离性能的影响.结果表明:Ti改性炭活性在1 100℃、N2保护焙烧后孔径分布更均一;CH4的吸附量达到34.4 mL/g,比未改性的活性炭和160℃水热方法 Ti改性的活性炭增加了51.5%;CH4常压穿透曲线的穿透点比未改性的活性炭和160℃水热方法 Ti改性的活性炭分别滞后了41%和50%.For methane （coal mine ventilation air methane） enrichment and separation, Ti modified method of activated carbon adsorption material （AC） was studied. The effect on separation performance of CHiN2 was discussed. The results show that pore diameter distribution of Ti modified activated carbon after roasting at 1 100 ℃ and N2 protection is more uniform; CH4 adsorption quantity reaches 34. 4 mL/g and increases 51.5% compared with unmodified activated carbon and Ti modified activated carbon at 160 ℃ hydrothermal method; CH4 breakthrough point of atmospheric breakthrough curve lags 41% and 50% respectively compared with unmodified activated carbon and Ti modified activated carbon at 160 ℃ hydrothermal method.
