A mathematical modeling and experimental study on adsorptive desulfurization of model gasoline using synthesized Ni-Y and Ce-Y zeolites

Abstract

In this study, Ni-Y and Ce-Y zeolites are prepared using synthesized Na-Y zeolite through solid-state ion-exchange method. The adsorptive desulfurization of a model gasoline containing 194, 116 and 72 ppmw sulfur is evaluated in a batch system under ambient conditions. A dynamic model is established in order to investigate the performance of the adsorption process. The model predictions are compared with the obtained experimental results for thiophene adsorption on Ni-Y and Ce-Y zeolites from model solution containing different concentrations of thiophene, and a good agreement is observed. The model parameters: diffusivity and mass transfer coefficient are estimated by comparing the model predictions and experimental data. © by De Gruyter 2014.
