Removal of Dibenzothiophene from Organic Medium by Modified Zeolite |
|
| چکیده انگلیسی مقاله |
In this research, adsorption of dibenzothiophene (DBT) as a model of sulfur containing material has been studied by Pb exchanged Y-zeolite under different experimental conditions. The adsorption was kinetically fast and high adsorption capacity was obtained. The equilibrium adsorption data were analyzed using Langmuir and Freunlich isotherm models. The corresponding parameters and correlation coefficients of each model are reported and the data was well fitted by the Langmuir isotherm. Pseudo-first order, pseudo-second order and intra-particle diffusion models were evaluated to examine the kinetic of the adsorption process. It was concluded that removal of DBT was obeys the second-order model of kinetic. The adsorbent was tested for five successive regeneration cycles and the considerable capacity of the adsorbent was remained after regeneration. |
