Outline of Final Research Achievements

The study investigated adsorption behavior of super-critical build. From the analysis of equilibrium adsorption of refrigerant R 32 on to activated carbon, the characteristic energy obtained by Dubinin-Astakhov equation was increased near critical temperature. The influence of super-critical state on the diffusion coefficient was more obvious, and the results implied that the adsorption state can be understood in more detail by analyzing the super-critical adsorption.
