Gs-phase adsorption isotherms and mass transfer characteristics of 1, 1-dichloro-1-fluoroethane (Hcfc-14 1b) by various adsorbents adsorbents

摘要

Experiments have been conducted to investigate gas-phase adsorption characteristics of 1, 1-di- chloro-1-fluoroethane (HCFC-141b) by activated carbon fiber (ACF), extruded activated carbon (EAC), granular activated carbon (GAC), activated alumina and molecular sieve. HCFC-14 1b is currently regarded as an excellent replacement for CFC-11, a foaming agent widely used in the rigid polyurethane foam industries.
