以油茶籽壳为原料，选择磷酸为活化剂，研究油茶籽壳活性炭的制备工艺。首先通过单因素试验确定液料比、炭化温度、活化温度、活化时间4个显著因素，再通过正交试验对油茶籽壳活性炭制备工艺进行优化。结果表明，选定活化剂磷酸的质量分数为60%，炭化时间为140 min时，制备油茶籽壳活性炭的最佳工艺条件是液料比3.0∶1，炭化温度200℃，活化温度550℃，活化时间60 min，活性炭产品的亚甲基蓝吸附值可达10.5 mL/0.1 g，碘吸附值为1461 mg/g，以上2个指标均达到木质净水用活性炭中的优级品要求。

The camellia oleifera seed shells is used as raw material and the phosphoric acid is chosen as activator to research the preparation technology of activated carbon. First, through the singer factor experiments, liquid-solid ratio, carbonization temperature, activation temperature and activation time are identified as four significant factors. Finally, the preparation technology of activated carbon of camellia oleifera seed shells is optimized by the orthogonal test. Under such conditions as the concentration of activator 60%, carbonization time 140 min, the optimum process conditions are as follows: liquid-solid ratio 3.0∶1, carbonization temperature 200 ℃, activation temperature 550 ℃, activation time 60 min. The methylene cyanine adsorption value of the activated carbon product is 10.5 mL/0.1 g, and the iodine adsorption value of the activated carbon product is 1 461 mg/g. The above two indexes all achieve the requirement of premium grade of the water purification with wooden activated carbon.
