Evaluation of the adsorption parameters

The values of the adsorption parameters used in this study were obtained as a result of the minimization of the sum of least squares deviation of calculated and experimental concentration profiles in a batch experiment [20]. The experimental concentration curve is given along with the calculated profiles (based on either the first-order or Langmuir kinetics) in Eigure 15.2. 

The first-order kinetics serves as a reference since it corresponds to the situation of weak adsorption. The concentration curve based on the Langmuir model followed the experimental trend more precisely and was, therefore, used in further modeling of the packed bed reactor. The adsorption parameters were treated as constants in all studies.
