摘　　要：以玉米秸秆酸水解残渣为原料、CO2为活化剂,制备了一系列活性炭,采用正交试验方法分析了原料颗粒大小、CO2/N2体积比、活化温度、活化时间4个因素对生物质水解残渣原料活性炭的比表面积、孔径和得率的影响。正交试验结果表明,活化温度和CO2/N2体积比是影响该类活性炭吸附性能的主要因素。制备的活性炭产品最大比表面积达到845.4m2/g,对应的制备工艺:原料颗粒50目、CO2/N2体积比1∶1、活化温度1000℃、活化时间210min。A range of activated carbons were prepared from corn stalk acid hydrolysis residue activated by carbon dioxide,The paper analyzes the influence of raw material particle size,CO2/ N2 volume,activation temperature and time on the specific surface area,pore size and yield of the activated carbons by orthogonal experimentation.The most important factors influencing carbon adsorbability were activation temperature and CO2/N2 volume.The maximum specific surface area of the activated carbon products was 845.4m2/g,the corresponding preparation method was 50 mesh raw material particle size,1 ∶ 1 CO2/N2 volume,1000℃ activation temperature and 210 minutes activation time.
