摘　　要：以高硫焦为原料 ,KOH作活化剂 ,按照四因素三水平L9(34)正交设计 ,制备出一系列超高比表面积活性炭。通过吸碘值进行正交实验结果分析 ,得出了高硫焦制备超级活性炭的最佳工艺条件及各活化因素对活化性能的影响。按最佳工艺条件制备出BET比表面积高达 3886m2 / g、微孔容量为 1 82ml/ g、孔径主要分布在0 4～ 0 8nm的超级活性炭。其活化工艺条件为活化温度 830℃、活化时间 1 5h、碱 /炭摩尔比 6∶1和原料粒度 10 0～ 15 4 μm。A series of activated carbons were prepared by chemical activation with L9(3 4) orthogonal design from high sulfur petroleum cokes. The optimum activated technology and the influence of every activation factor to the properties of activated carbon were found out by orthogonal test analysis with the value of adsorbed iodine. Chemically activated carbon, of which the BET surface area is 3886 m 2/g and the micro porous volume 1 82 ml/g, was produced at the conditions of 830 ℃ activation temperature, 1.5 h activation time, 6∶1 of alkali /carbon and 100～154 μm particle size.
