摘　　要：采用水蒸气物理法制备小桐子壳基活性炭,通过响应曲面法中模型的优化设计和分析,研究了制备过程中的3个影响因子(活化温度、活化时间以及水蒸气流量)对活性炭碘吸附能力和得率的影响,并通过方差分析(ANOVA)研究了各个实验因子或交互作用对活性炭性能的影响。经过优化所获得的实验条件为:活化温度900℃,活化时间22min,水蒸气流量5.5g/min,获得的活性炭碘值为950mg/g,得率为13%,比表面积为785m2/g。Preparation of activated carbon by jatropha hull with steam was mainly studied using response surface methodology for optimization and analysis.The effects of three preparation variables including the activation temperature,activation time and steam current capacity on the properties of activated carbon were investigated from the analysis of variance （ANOVA） and the significant factors on each experimental design response were identified.The optimum activated carbon prepared from jatropha hull was obtained using activation temperature of 900 ℃,activation time of 22 min and of steam current capacity of 5.5 g/min,the iodine adsorption value and rate were 950 mg/g and 13％ respectively,the surface area was 785 m2/g.
