以油茶壳为原料,对未酸洗、酸洗和酸洗＋碳酸钾处理后制得的活性炭的性能进行比较。讨论了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,未酸洗和酸洗＋碳酸钾产品的吸附性能呈不断下降的趋势;酸洗产品的吸附性能随着炭化温度的升高呈不断上升的趋势;800℃时,未酸洗和酸洗＋碳酸钾产品的吸附性能比酸洗的高;随着保温时间的延长,3种产品的吸附性能均呈不断上升的趋势。

Shells of Camellia oleifera Abel which were untreated,treated by acid and treated by acid and potassium carbonate were used as raw materials to prepare activated carbon.Properties of these three kinds of activated carbon were investigated.The effect of parameters such as temperature and holding time on the yield,methylene blue and iodine of activated carbon were studied.The result showed that the adsorption capacities decreased with rising carbonization temperature for the product made by shells untreated and treated by acid and potassium carbonate;the adsorption capacities increased with rising carbonization temperature for the product made by shells treated by acid;the adsorption capacities of the product made by shells untreated and treated by acid and potassium carbonate was higher than that of treated by acid at 800 ℃;the adsorption capacities of the three products increased with holding time.
