| 摘 要： | 采用了动态吸附实验方法研究了吸附树脂NDA-201和椰壳型活性炭C1对苯蒸汽的吸附行为.对吸附平衡数据采用Dubinill-Astakov方程进行了拟合分析,并根据吸附剂孔结构特征探讨了吸附机理.实验结果表明,两种吸附剂的苯吸附等温线存在交叉现象,对高浓度苯蒸汽吸附治理可采用NDA-201树脂,低浓度则采用椰壳型活性炭C1;Dubinin-Astakov方程能用来对两种吸附剂的等温线进行拟合,表明吸附剂的微孔区域对吸附起着重要作用.微孔体积计算值的比较和特征曲线叠合的程度说明了.Polanyi吸附势理论更适合于描述椰壳型活性炭C1对苯的吸附,这可能是由于椰壳型活性炭C1的孔分布集中于微孔区,而NDA-201树脂除了微孔外还有一定量的中孔和大孔. |

| Abstract: | A dynamical adsorption approach was used to study the benzene vapour onto two adsorbents including of a hypercrosslinked polymer NDA-201 and a coconut activated carbon C1. Dubinin-Astakov equation,a nonlinear isotherm model was tested to fit experimental data. Based on the pore structure analysis of two adsorbents,adsorption mechanism was discussed. Experimental results indicated that the intersection of adsorption isotherms of two adsorbents was found. The adsorption equilibrium data of benzene on two adso... |
