1,1-Dichloro-1-fluoroethane (HCFC-141b) is current recognized as an excellent substitute for chlorofluorocarbons (e.g., CFC-11 and CFC-113). In the present work fixed-bed adsorption studies were performed on the use of granular activated carbon (GAC) and activated carbon fiber (ACF) for the recovery of HCFC-141b vapor from air. Adsorption equilibria were obtained at 283, 293, 303, and 313 K. Three classic models (Langmuir, Freundlich, and Dubinin-Radushkevich) were applied and their parameter constants were determined by regression analysis. It was found that these isotherms were fitted well by the measured adsorption data, and the determined parameters of isotherm equations were consistent with the physical properties (e.g., specific surface areas and pore volumes) of these carbon adsorbents. It is clear that the performance of adsorbent ACF is significantly better than that of adsorbent GAC in terms of the adsorption capacity and the adsorption rate. A simple two-parameter model, originally introduced by Yoon and Nelson, was adopted to describe the entire breakthrough curves regarding the adsorption of HCFC-141b vapor through carbon columns at 283 K. The results indicate that the calculated breakthrough curves agree well with the corresponding experimental data.
