A kinetic study of organic compounds (acetone, toluene, n-hexane and n-decane) adsorption behavior on activated carbon under supercritical carbon dioxide conditions at temperature from 313 to 353Â K and at pressure from 4.2 to 15.0Â MPa

- Adsorption kinetics of organic compounds on activated carbon in supercritical carbon dioxide was studied.
- The measured breakthrough curves could be well correlated with a kinetic model.
- The determined diffusion coefficients were strongly dependent on temperatures and pressures conditions.
- Predictive possibility of the diffusion coefficients was suggested by using the proposed model.
