    Adsorption of Chlorobenzene from Mixed Gas on Activated Carbon Fixed Bed

      摘要
    • 摘要: 研究了氯苯气体在活性炭固定床上的吸附过程。对不同温度下氯苯在活性炭中的吸附特性进行了测定,并用过热蒸气对活性炭吸附的氯苯进行了脱附回收。采用线性平衡吸附体系的动力学模型对实验数据进行关联,得到了活性炭吸附氯苯的总传质系数和吸附带长度。结果表明:吸附温度升高时,总传质系数减小,吸附带长度增大。根据模型计算得到的穿透曲线与实验结果进行比较,两者吻合较好。

       

      Abstract: Adsorption of chlorobenzene from mixed gas by activated carbon was studied on fixed bed.Adsorption characteristics under different temperatures were measured by experiments,and the absorbed chlorobenzene in activated carbon was desorbed and reclaimed by overheated water vapor.The experimental data were correlated with dynamic models based on linear equilibrium,overall mass transfer coefficient and length of adsorption zone were obtained.The results show that overall mass transfer coefficient(decreases) but length of adsorption zone increases with an increase in adsorption temperature.The breakthrough curves were calculated by the model.The calculation results agree well with experimental data.
