    • Porous carbon fibers, whose active centers are formed by pores that are filled at least in part by carbon and/or metal and/or metal carbide, obtainable by carbonization of organic or inorganic polymers, the use thereof for the adsorption or separation of gaseous substances, in particular of CO2, and also a method for the production thereof. First, a spinning mixture containing polyacrylonitrile-based polymer A and an organic or metallo-organic polymer B is produced. Next, the spinning mixture is spun to form mixed fibers of polymer A and polymer B. The mixed fiber is stabilized by oxidation. This is followed by carbonization or graphitization of the mixed fiber under non-oxidizing conditions in such a way that the polymer B forms a carbon and/or metal and/or metal carbide residue of at least 22 wt %, the residue forming active centers.
    • 多孔碳纤维,其活性中心由至少部分由碳和/或金属和/或金属碳化物填充的孔形成,可通过有机或无机聚合物的碳化获得,其用于吸附或分离气态物质 ,特别是二氧化碳,以及其制备方法。 首先,制备含有聚丙烯腈类聚合物A和有机或金属有机聚合物B的纺丝混合物。 接下来,将纺丝混合物纺丝以形成聚合物A和聚合物B的混合纤维。混合纤维通过氧化而稳定。 接着在非氧化条件下使混合纤维碳化或石墨化,使得聚合物B形成至少22重量%的碳和/或金属和/或金属碳化物残余物,残余物形成活性中心。
