Abstract

This paper presents theoretical and experimental adsorption kinetics of Difluoromethane (HFC-32) onto activated carbon powder of type Maxsorb III and activated carbon fiber of type A-20. The experimental runs have been conducted on an apparatus that has been designed and built specially for this purpose. The adsorption kinetics have been determined at different adsorption temperatures ranging from 25°C to 65°C. The experimental data are reduced and fitted with linear driving force (LDF) and Fickian diffusion (FD) models. It has been found that both LDF and FD models are able to simulate the adsorption kinetics of HFC-32 onto activated carbon powder and fiber with an error of ±5%.
