摘要：

Experimental and theoretical adsorption isotherms and kinetics data of HFC410A onto activated carbons are reported. Activated carbon powder of type Maxsorb III and activated carbon fiber of type A-20 have been used as adsorbents. An experimental apparatus has been designed and built and experimental investigation has been carried out at five adsorption temperatures in the range of 10-50 degrees C Experimental data has been fitted with Toth and Dubinin-Astakhov (D-A) adsorption isotherm models and linear driving force (LDF) adsorption kinetics model. A range of adsorption parameters such as isosteric heat of adsorption, adsorption uptake and temperature dependence and Henry's law coefficients are evaluated. A correlation between Henry's law coefficients and isosteric heat of adsorption at limiting uptake is analyzed. (C) 2014 Elsevier Ltd. All rights reserved.
