微波加热与传统加热制备高比表面活性炭的对比研究

Comparing Properties of Activated Carbon Prepared by Microwave Heating Method with Those Prepared by Conventional Heating Method

以中间相炭微球为原料,KOH为活化剂,采用微波加热与传统加热2种方法在不同条件下制备出高比表面积活性炭。研究表明:活性炭比表面积和孔容随着KOH/MCMB的增大先增大后减小,采用微波加热制得的活性炭具有较高的比表面积,KOH/MCMB较小时,比表面积和孔容随活化时间的延长达到最大值后不再发生变化,在KOH/MCMB较大时,比表面积和孔容随活化时间的延长先增大后减小,采用微波加热可大大缩短活化时间,通过FTIR分析,微波加热比传统加热所制得的活性炭具有较低浓度的含氧基团。

To our knowledge,there is no paper in the open literature dealing with comparing properties of activated carbon prepared by microwave heating and conventional heating.Section 1 of the full paper briefs our experimental setup,whose schematic,presented in Fig.1,includes 11 explanatory notes,and experimental method.We point out that explanatory note No.5 is particularly important for making our experiments succeed.Section 2 presents experimental results and their discussion.Figs.2 and 3 present the results res...
