Abstract

The objective of this article is to evaluate adsorption kinetics of R134a and R507A on pitch based activated carbon experimentally by a constant volume variable pressure method at different adsorption temperatures ranging from 20 to 60 °C. These data are useful for the design of adsorption cooling and refrigeration systems and are unavailable in the literature. Data obtained from the kinetic studies were analyzed with various kinetic models and the Fickian diffusion model is found to be the most suitable overall. Guided by the experimental measurements, the surface diffusion is also estimated and is found that it follows the classical Arrhenius law within the experimental range.
