  • 摘要: 以印染污泥和木屑为混合原料,以NaOH为活化剂,通过化学活化法制备活性炭.对活化温度、活化时间和活化剂与基质混合比3个因素进行了研究,并采用中心组合设计(central composite design,CCD),建立了相应的二次方程.从响应曲面的方差分析中确立了对响应值影响最显著的因素依次为:活化温度、NaOH基质比和升温速率.其最佳工艺参数分别为:活化温度739℃,升温速率6.59℃/min, NaOH基质比为2.51.在最佳条件下制得碘吸附值为1 518.89 mg/g,BET比表面积为1 617.70 m2/g的活性炭.
    Abstract: Textile dyeing sludge and sawdust were used to produce activated carbon with NaOH activation method.The effects of activation temperature,heating rate and NaOH/precursor ratio on the influence of iodine number were investigated.Based on the central composite design (CCD),quadratic model was developed to correlate the influential factors to the iodine number.From the analysis of variance,the most influential factor on iodine number were sorted the results followed by activation temperature,NaOH/precursor ratio and heating rate.The optimum conditions were as follows:temperature of 739℃,heating rate of 6.59℃/min and NaOH/precursor ratio of 2.51 g,which resulted in 1 518.89 mg/g of iodine number,and with a BET surface of 1 617.70 m2/g.
