摘要

摘要: 采用KOH对橄榄渣进行活化得到活性炭。设计2³正交试验来优化制备工艺条件，水平和因子包括活化温度（600，900℃）、活化时间（1，3 h）和浸渍比（1∶2，1∶4）。活性炭的比表面积作为优化的评价指标。通过氮吸附仪、红外光谱仪和扫描电镜等手段对活性炭的表面化学和孔结构进行表征。结果表明，所有因子及其交互水平都非常显著（p<0.05）。活性炭的比表面积和制备条件的相关系数为99.2%。在最条件下制备的活性炭，比表面积为672 m²/g、平均孔径为2.05 nm，微孔和介孔率分别为81.36%和18.37%。

Abstract: Activated carbons were prepared from olive cake waste by KOH activation. A full factorial 2³ experimental design was used to optimize their preparation conditions. The factors and levels included are activation temperature (600 and 900℃), activation time (1 and 3 h) and impregnation ratio (1:2 and 1:4). The surface area of the activated carbons was chosen as a measure of the optimization. The surface and pore properties of the activated carbon obtained at the optimum conditions were characterized by nitrogen adsorption, infrared spectroscopy and scanning electron microscopy. Results indicated that all factors and their interactions are significant (p<0.05). A function was used to correlate the surface area of the activated carbons to their preparation conditions with a correlation coefficient of 99.2%. The activated carbon prepared at the optimum conditions has a BET surface area of 672 m²/g and an average pore size of 2.05 nm with micro and mesopore volumes of 81.36 and 18.37%, respectively.
