    • The present invention is a preparation method for asphalt-based spherical activated carbon which requires no infusibilization process. Placing coal tar asphalt into a melting device; introducing compressed air of 0.1 MPa-0.5 MPa into the device and stirring until a melting temperature of 280° C.-350° C. is reached; continuing for 2-8 hours until the base material has a softening point of 200° C.-260° C.; after cooling down, pulverizing the base material to obtain asphalt powder. Obtaining 34%-79% by mass of carbon powder, 1%-10% by mass of binder, and 20%-65% by mass of the asphalt powder and then forming spherical particles with a diameter of 0.5 mm-5 mm with the carbon powder, the binder and the asphalt powder at room temperature. Introducing the spherical particles of asphalt directly into an asphalt carbonization furnace for carbonization at a temperature of 600° C.-900° C. under protection of an inert gas to obtain asphalt spherical carbon. Asphalt spherical carbon is subject to activation treatment to obtain asphalt spherical activated carbon. The preparation method of the present invention reduces processing difficulty and production costs significantly.
    • 本发明是一种沥青基球形活性炭的制备方法,不需要进行渗透处理。 将煤焦油沥青放入熔化装置; 将0.1MPa-0.5MPa的压缩空气引入装置中并搅拌直到达到280℃-350℃的熔融温度; 继续2-8小时,直到基材的软化点为200℃-260℃。 冷却后,粉碎基材,得到沥青粉。 得到34%〜79质量%的碳粉,1质量%-10质量%的粘合剂和20%-65质量%的沥青粉,然后形成直径为0.5毫米-5毫米的球形颗粒, 碳粉,粘合剂和沥青粉末在室温下。 将沥青的球形颗粒直接引入沥青碳化炉中,在600℃-900℃的温度下进行碳化,保护惰性气体得到沥青球形碳。 沥青球形碳经活化处理得到沥青球形活性炭。 本发明的制备方法显着降低了加工难度和生产成本。
