Augelletti R., Frattari S., Annesini M., 2016, Isopropyl Alcohol Vapour Removal from Diluted Gaseous Stream by Adsorption: Experimental Results and Dynamic Model, Chemical Engineering Transactions, 47, 451-456.
The gas phase adsorption of isopropyl alcohol (IPA) onto a commercial activated carbon at 30 °C was investigated under different operating conditions. Fixed-bed experiments were performed to obtain equilibrium and kinetic data for IPA adsorption. The equilibrium data were fitted by means of the Langmuir equation and isotherm parameters were determined. A dynamic, isothermal, dilute solution adsorption model, based on the linear driving force (LDF) approximation, was developed to describe the kinetic adsorption behavior. A very good agreement between experimental and model results was found when a LDF mass-transfer-rate coefficient dependent on the gas concentration was used.
