Cr, Fe-MOF/ Graphene Hybrid Nanocomposite for Ultra Removal of Organic Sulfur Compounds from Diesel Fuel

Article scientifique 2022 Anglais

Résumé

Abstract Metal-organic frameworks (Cr-MOF and Fe-MOF) and their graphene hybrid nano-composites were prepared via the green solvo-thermal method. The prepared samples were characterized by XRD, FTIR spectroscopy, N2 adsorption-desorption isotherm, and XPS. The composites were used for the adsorption of thiophenic sulfur compound (thiophene, dibenzothiophene, 4,6-dimethyldibenzothiophene) in a model fuel oil. It was found that graphene in the MOF composite has a positive effect on sulfur removal. The removal efficiency increase from 62 % to % 95.6 using Fe-MOF and Fe-MOF/Gr (9:1), respectively. This enhancement effect is attributed to a higher number of coordinatively unsaturated sites (CUS) in the composites. The results indicated that the adsorption reaches to 96.6% for DBT adsorption from model diesel oil and 62% for diesel fuel on using Cr-MOF/Gr composite.
