Adsorption of Chlorobenzene from Mixed Gas on Activated Carbon Fixed Bed

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.
