Liquid-phase adsorption of 1,1-dichloro-1-fluoroethane by various adsorbents

Experiments have been conducted to examine the liquid-phase adsorption/desorption characteristics of 1,1-dichloro-1-fluoroethane (HCFC-141b) by activated alumina, molecular sieve, granular activated carbon (GAC), extruded activated carbon (EAC), and activated carbon fiber (ACF). HCFC-141b is currently regarded as an excellent replacement for CFC-11. The experimental results of adsorption and desorption were analyzed in terms of the equilibrium adsorption capacity, time to reach equilibrium, and desorption efficiency of the adsorbent and with an aim to assess the viability of the use of all adsorbents for possible HCFC-141b recovery. Adsorption isotherms of the Langmuir and Freundlich types were employed to examine the equilibrium adsorption data. A mass-transfer model based on the pseudo-steady-state driving force was adopted to describe the HCFC-141b adsorption process.
