【摘要】 本文采用沥青基炭纤维为原料制备活性炭纤维,研究了氨盐浸渍预处理对活性炭纤维得率、比表面积、孔结构及甲烷吸附性能的影响。结果表明,经氨盐处理的活性炭纤维其甲烷吸附量并未随比表面积增加而提高,活性炭纤维的甲烷吸附量不仅与比表面积而且与孔结构有关。更多还原

【Abstract】 Activated carbon fibers（ACF） are prepared from pitch based carbon fibers by （H₂O+CO₂） activatingprocess. The influences of ammonium salt soaking on ACF adsorption properties were studied. The results show thatthe CH₄ adsorption amount of ACF pretreated with ammonium salt does not increase with surface area increase. Theadsorption amount not only depends on surface area but also pore structures.更多还原
