摘要：

Theoretical and experimental investigations were conducted on the adsorption characteristics of 1,1,1,2-tetrafluoroethane (HFC-134a) by granular and extruded activated carbons (GAC and EAC). HFC-134a is currently regarded as an excel-lent replacement for CFC-12 (Freon 12), a refrigerant previously used in all automobiles and many cooling systems. Experimental results of column adsor-ption were employed to verify the theoretical breakthrough curves generated from the pro-posed model and excellent model fit of the breakthrough curves of HCFC-134a adsorption were obtained. Investigations were also made on the effects of gas velocity, inlet HFC-134a concentration and operating temperature on the adsorption efficiency.
