摘要: 以承德华净活性炭有限公司的椰壳炭化料为原料，对椰壳基炭化料在不同温度下进行预处理，研究了炭化料粒径、预处理工艺、活化方法(CO2物理法、KOH化学法)、活化温度、活化时间等对椰壳基活性炭孔结构的影响。在400℃预处理、碱炭比2:1、活化温度850℃、活化时间1 h条件下，制备出比表面积为2074 m2/g、中孔发达的椰壳基活性炭。
Abstract: Carbonized material based coconut shell taken from Chengde, Huajing Activated Carbon Co., LTD., was used as raw material, and preprocessed at different temperature. The influence from particle size of carbonized material, pretreatment process, activation method (CO2 physical method, KOH chemical method), activation temperature, activation time on pore structure were studied. The developed amid hole structure activated carbon based coconut shell with specific surface area of 2074 m2/g was prepared at pretreatment temperature of 400˚C, the ratio of alkali and carbon of 2:1, activation temperature of 850˚C, activation time of 1 h.
