The preparation of activated carbon from an economically sustainable precursor Limonia acidissima shell (an agricultural waste) by chemical activation method has been explored in the present study. This investigation emphasizes the application of a statistical tool, Response surface methodology (RSM) coupled with Box-Behnken design (BBD) to optimize the experimental conditions for the preparation of activated carbon from lignocellulosic wastes activated with ZnCl₂. The chemical activation is conducted at a different combination of impregnation ratios (IR), activation time and carbonization temperatures as suggested by the Design Expert software. The influences of these parameters on the responses i.e. iodine no. and yield of activated carbon has been investigated. Simultaneous optimization is performed using desirability approach. The desirability value reported for AC-ZnCl₂ is 0.653. The carbon yield and iodine adsorption value approached 49.67% and 928.58 mg/g under the optimal conditions of impregnation ratio (1), activation time(57.09 min),and carbonization temperature (436.52°C). Important physicochemical properties of the optimized activated carbon is further confirmed by FTIR analysis, TEM analysis etc.

使用Box-Behnken设计对氯化锌活化生物质进行统计优化

在本研究中，已经探索了通过化学活化方法从经济上可持续的前驱酸柠檬衣壳（一种农业废物）制备活性炭的方法。这项研究着重于应用统计工具，响应面方法（RSM）和Box-Behnken设计（BBD）来优化由ZnCl ₂活化的木质纤维素废物制备活性炭的实验条件。。如Design Expert软件所建议的那样，化学活化是在浸渍比（IR），活化时间和碳化温度的不同组合下进行的。这些参数对反应的影响，即碘号。并且已经研究了活性炭的产率。使用期望方法执行同时优化。报告的AC-ZnCl ₂的合意值为0.653。在最佳的浸渍比（1），活化时间（57.09 min）和碳化温度（436.52°C）下，碳收率和碘吸附值分别达到49.67％和928.58 mg / g。优化的活性炭的重要理化性质通过FTIR分析，TEM分析等得到进一步证实。
