| 摘 要： | 以油茶壳为原料,采用直接炭化和二步炭化法制备活性炭,探讨炭化温度和保温时间对活性炭产品得率、亚甲基蓝吸附值和碘吸附值的影响。研究结果表明,随着炭化温度的升高,直接炭化法制得的油茶壳活性炭的吸附性能呈先升后降的趋势;二步炭化法随着保温时间的延长,活性炭的吸附性能呈不断上升的趋势,在较优的工艺条件下,活性炭的亚甲基蓝吸附值和碘吸附值为210.0 mg.g-1和1 016.2 mg.g-1。二步炭化有利于进一步提高直接炭化的油茶壳活性炭的吸附性能,制得吸附性能良好的活性炭材料。

| Abstract: | Shells of Camellia oleifera Abel were used as raw materials to prepare activated carbon by direct carbonization process and two-step carbonization process.The main parameters such as temperature and holding time were studied to show the effect on the yield,methylene blue adsorption value and iodine adsorption value of activated carbon.The results showed that the adsorption capacities increased to a peak and the decreased with rising carbonization temperature on the direct carbonization process;the adsorptio... |
