摘要
以甘蔗糖厂废弃的蔗渣为活性碳的生产原料,以磷酸作为活化剂生产活性炭,探索了生产活性炭的工艺条件。结果显示,最佳工艺条件为:陈化时间9 h、炭化温度300℃、炭化时间120min、活化温度400℃。活性炭的焦糖脱色率、亚甲基蓝吸附值两项指标均达到一级品的要求。
Activated carbon was prepared from bagasse by H3 P04 activation. The preparation technology of bagasse-based activated carbon was optimized. The result showed that the optimal technological conditions were obtained and the caramel decolorization rate and the adsorption values of methylene blue all reached the request.
