Abstract：
This paper reports the use of naturally available raw material as sugarcane bagasse (SB) to prepare cost-effective activated carbon. Activated carbon preparation from SB by using ZnCl2 was carried out by chemical activation method. The raw bagasse, its char and activated carbon were characterized on the basis of iodine number, carbon, hydrogen, nitrogen analysis, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and Brunauer-Emmett-Teller (BET) surface area to check their effectiveness. During activated carbon synthesis, the impregnation ratio of SB and ZnCl2 was maintained at 1:1-1:3 and activation temperature was in the range of 600-900 °C for 1 h. From the characterization study, the highest iodine adsorption of activated carbon was found to be 1140.69 mg/g with a 1:2 ratio at 900 °C whereas char gives an iodine number of 529.63 mg/g at the same temperature. The BET surface area of raw bagasse, its char and activated carbon (SB-Zn2-900) obtained was 4.30, 514.27 and 1386.58 m2/g, respectively, which shows charrification and chemical activation improves surface area. The optimum ratio of impregnation and activation temperature was found to be 1:2 at 900 °C. In this work, activated carbon was successfully prepared and obtained product has better characteristics than previously reported studies.
摘要：
本文报道了使用天然可用的原料作为甘蔗渣（SB）来制备具有成本效益的活性炭。采用化学活化法,利用ZnCl2从SB制备活性炭。生甘蔗渣，根据碘值对其炭和活性炭进行了表征，碳,氢气,氮分析,傅里叶变换红外光谱(FTIR),扫描电子显微镜（SEM），热重分析（TGA）和Brunauer-Emmett-Teller（BET）表面积检查其有效性。在活性炭合成过程中,SB和ZnCl2的浸渍比保持在1:1-1:3，活化温度在600-900°C的范围内持续1小时。在900°C时，活性炭的最高碘吸附率为1140.69mg/g，比例为1：2，而在相同温度下，炭的碘值为529.63mg/g。原甘蔗渣的BET表面积，获得的炭和活性炭(SB-Zn2-900)为4.30、514.27和1386.58m2/g，分别,这表明炭化和化学活化提高了表面积。发现在900°C时浸渍和活化温度的最佳比例为1:2。在这项工作中,成功地制备了活性炭，获得的产品比以前报道的研究具有更好的特性。
