摘要

摘要: 以椰壳纤维为原料，制备高比表面积中孔活性炭。采用正交试验设计实验方案，研究KOH和NaOH复合活化法制备活性炭的实验方案与工艺条件。考察了活化剂配比、炭化温度、活化温度、时间和升温速率对所制活性炭吸附性能的影响。在最佳工艺条件下，所制活性炭的比表面积达到2032m²/g，中孔发达，特别是2nm~4nm的，中孔比例达到28%。活性炭对的碘吸附值为1435mg/g，亚甲基蓝吸附值为495mg/g，产率为49%。

Abstract: Activated carbons (ACs) with high specific surface area and abundant mesopores were prepared from coconut shell fibers through carbonization and NaOH/KOH activation. The influence of NaOH/KOH ratio, carbonization temperature, activation temperature, activation time and heating rate on the adsorption behavior of the ACs were investigated. The specific surface area of the obtained ACs under optimum conditions was 2032m²/g with 28% （volume fraction） of mesopores between 2 to 4nm. The iodine adsorption value and methylene blue adsorption value of the AC were 1435 and 495mg/g, respectively.
