摘要/Abstract

摘要： 以碱木质素为原料采用球形木质素前驱体,炭化,活化三步法制备微米尺寸的球形活性炭。研究了球形木质素前驱体的制备条件及活化条件对球形活性炭的粒径大小、结构形貌、孔结构的影响;采用扫描电子显微镜(SEM)、低温N₂吸附-脱附以及傅里叶红外光谱(FT-IR)对产物的形貌结构、吸附性能和表面官能团进行了表征。结果表明,当反应温度为90 ℃,反应时间10 h,搅拌速度200 r/min,pH值为3.0的条件下,制备出粒径为5 μm左右、球形形貌完整的球形木质素前躯体。通过对球形木质素前躯体在 300 ℃炭化以及850 ℃下CO₂活化,制备出比表面积为776.96 m²/g,总孔容为0.487 1 cm³/g,平均孔径为2.51 nm的球形活性炭。

Abstract: Spherical activated carbon was prepared from the industrial alkali lignin via three steps:preparation of spherical lignin precursor, carbonization, and activation. Effects of preparation and activitation conditions of spherical lignin precursor on its morphology and particle size of the spherical activated carbon were investigated. SEM, N₂(77K) adsorption-desorption isotherm, and FT-IR were used for characterizing its morphology structure, adsorption property, and surface functional groups, respectively. The results showed that spherical lignin precursor with diameter of approximate 5 μm could be obtained under the reaction temperature 90 ℃, stirring rate 200 r/min, reaction time 10 h, and pH 3.0. After carbonization at 300 ℃ followed by activation at 850 ℃, spherical activated carbon with BET surface area of 776.96 m²/g, total pore volume of 0.487 1 cm³/g, and average pore diameter of 2.51 mm could be obtained.
