摘要：

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　CH4/N2　was　discussed.　The　results　show　that　pore　diameter　distribution　of　Ti　modified　activated　carbon　after　roasting　at　1100°C　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°C　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°C　hydrothermal　method.
