Coal pitch was used as raw material to produce coal pitch spheres by suspension method,the coal pitch spheres were then turned to spherical activated carbon by processes which including stabilization,carbonization and activation in the experiment.
以煤沥青为主要原料采用悬浮法制备含致孔剂的煤沥青球后进行预氧化、炭化和活化,最终得到沥青基球形活性炭(PSAC)。
The formation of pitch spheres is the key step of PSAC preparation,because the characteristics of pitch spheres will affect the properties of PSAC.
沥青球的制备是球形活性炭制备的关键步骤 ,制备的沥青球的软化点、球形度等指标直接影响目的产品球形活性炭的物性指标。
Pre\|activated pitch\|based carbon spheres were impregnated in aqueous solution of different metallic salts to prepare the pitch spheres containing metal.
将预活化的沥青基炭球在不同金属盐的水溶液中浸渍，使之负载有金属，然后进行活化处理。
