摘要:
 对MH Y30 型活性炭进行水蒸气活化, 采用H NO3 氧化和H 2O2 氧化两种方法进行改性, 在水洗脱附
的条件下, 对改性前后活性炭的表面分形维数进行了实验测试, 并对渗透率的影响因素进行了分析.实验结果
表明, 水洗脱附条件下活性炭的分形维数与反应中间过程中能被有效利用的吸附场所密切相关, H 2O2 改性
方法能有效提高分形维数和活性炭吸附性能, 而表面分形维数相同时, 粒子单元横截面积和粒子链最大直径
对渗透率产生较大影响.
Abstract:
Surface fractal dimensions of M HY30 activated car bo n r eactivated with steam and modified by H NO3 and H 2O2
hav e been investig ated under the co nditio n of de so rbing by wa te r .Influence facto r o f activated carbon’ s pe rmeability is a nalyzed.
Results show that the surface fr acta l dimension of ac tivated carbon is clo sely related to the effective adso rptio n sites
in the reaction pr ocess.Fr acta l dimensio n and adso rptio n perfo rmance o f ac tivated car bo n can be impro ved by H 2O2 modifica
tion .The cr oss-sectio n a rea of par ticle unit and the ma ximum diameter of par ticle chain may have g reat influences on
activated ca rbon’ s pe rmeability w he n surface fractal dimensio n is identical.
