摘　　要：以大同烟煤和陕西府谷煤为原料进行实验,利用水蒸气活化法,制备不同配比的具有较高焦糖脱色率的压块活性炭。实验结果表明:在大同煤:府谷煤质量比为6:4,炭化温度550℃、活化温度930℃、烧失率73.5%的条件下,制得的活性炭性能较佳,其指标分别为强度98%,碘吸附值1 130 mg/g,亚甲基蓝吸附值260 mg/g,焦糖脱色率达到98%。Taking Datong bituminous coal and Shaanxi Fugu coal as the raw material,the experiment utilized steam activation process to prepare the agglomerated activated carbon of different proportions,used for caramel decolorization. The results showed that when the ratio of Datong bituminous coal and Shaanxi Fugu coal was 6：4, the carbonization temperature was 550 ℃ ,the activation temperature was 930℃ and the burn-off rate was 73.5% ,the adsorption properties of activated carbon were better and its strength was 98%, iodine adsorption was 1 130 mg/g, methylene blue adsorption was 260 mg/g, and caramel decolorization rate was 98%.
