摘　　要：以煅前石油焦为原料,采用KOH化学活化法制备超级电容器用高比表面积活性炭,通过考察碱炭比、活化温度、活化时间和原料预处理方式对活性炭结构和性能的影响,探讨了影响高比表面积活性炭结构和性能的主要因素,确立了制备超级电容器用高比表面积活性炭的最佳工艺条件。Activated carbons with high specific surface area for supercapacitors were prepared from uncalcined petroleum coke as raw materials by KOH chemical activation. The effects of the ratio of alkali to carbon, activation temperature, activation time and raw material pretreatment on the structure and properties of the activated carbons were investigated. The optimum conditions for prepara- tion of activated carbon with high specific surface area were achieved.
