Desulfurization of model gasoline using metal organic frame-work

Abstract

This work is to study the batch adsorption desulfurization process for model gasoline (isooctane + thiophene) and to prepare low-cost adsorbent MOF-199 for desulphurization of model fuel by adsorption. A MOF-199 (metal-organic framework) was prepared under solvothermal conditions and characterized with a BET surface area and a powder X-ray diffraction. The effect of concentration of thiophene, adsorbent dose, contact time, and the temperature was investigated in Batch process for model gasoline. The residual sulfur concentration in model fuel was decreased from 1500 to 148.2 ppm. Corresponding to a removal efficiency of 90.12 %, at optimum conditions for contact time 4 hours. The experiment showed that MOF-199 was effective in removing the thiophene as well as its reusability.
