| 摘 要： | 以CO2为活化气氛，通过一步快速热解活化法从黑山煤粉与生物质混合物中制取活性炭。讨论了不同质量比率、活化温度和CO2浓度对活性炭比表面积的影响。通过N2吸附（BET）、扫描电镜（SEM）、拉曼光谱（Raman）和红外光谱（FTIR）对活性炭的性能进行了表征。确定了制备活性炭的最佳条件为活化温度900℃、质量比1、CO2体积分数30%、活化时间120min时，活性炭的比表面积和孔容最大，分别为901m2/g和0.39cm3/g。最后，用乙酸乙酯吸附量验证了其吸附性能，最大累积吸附量为766.51mg/g。 |

| Abstract: | Activated carbon was prepared from the mixture of Heishan coal powder and biomass by one step rapid pyrolysis activation method with CO2 as activation atmosphere. The effects of different mass ratio, activation temperature and CO2 concentration on the specific surface area of activated carbon were discussed. The properties of activated carbon were characterized by N2 adsorption (BET), scanning electron microscopy (SEM), Raman spectroscopy (Raman) and infrared spectroscopy (FTIR). The optimum conditions for preparation of activated carbon were determined as follows: when the activation temperature was 900℃, the mass ratio was 1, the concentration of CO2 was 30%, and the activation time was 120min, the specific surface area and pore volume of activated carbon were the largest, which were 910m2/g and 0.39cm3/g, respectively. The adsorption capacity of activated carbon was verified by the adsorption capacity of ethyl acetate, and the maximum cumulative adsorption capacity was 766.51mg/g. |
