Abstract
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
