| 摘 要： | 对MHY30型活性炭进行水蒸气活化,采用HNO3氧化和H2O2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,H2O2改性方法能有效提高分形维数和活性炭吸附...

| Abstract: | Surface fractal dimensions of MHY30 activated carbon reactivated with steam and modified by HNO3 and H2O2 have been investigated under the condition of desorbing by water.Influence factor of activated carbon's permeability is analyzed.Results show that the surface fractal dimension of activated carbon is closely related to the effective adsorption sites in the reaction process.Fractal dimension and adsorption performance of activated carbon can be improved by H2O2 modification.The cross-section area of part... |
