Enhanced Desulfurization of Fuel Oil: Investigating The Efficacy Of Cerium-doped Iron Vanadate

Abstract

The escalating environmental concerns due to the advancement of modem technology and industrialization have prompted the need for effective pollution reduction strategies. One such solution is the utilization of catalysts to upgrade oil quality by transforming sulfur content in a process known as aerobic adsorption desulfurization. These catalysts have consequently gained considerable recognition in this field. In this study, cerium doping was employed with iron vanadate for the aerobic adsorptive desulphurization process. The potency of the catalyst was enhanced through the use of a one pot hydrothermal synthesis method to homogeneously disperse the components onto the material surface. The oil was significantly boosted, resulting in an increase of98% in the removal rate. The pseudo-first order reaction kinetics manifested that the use of the dopant enhance the catalyst's efficacy by 98%, resulting in the production of green fuel. The composition, shape, and properties of the catalyst were then evaluated through Energy dispersive X-ray spectroscopy, X-ray diffraction, and scanning electron microscopy. To optimize the catalyst's effectiveness, multiple parameters such as the amount of oxidizing reagent, catalyst quantity, and reaction temperature were varied. By fine-tuning the reaction conditions, which involved employing a 40 mg catalyst, utilizing molecular oxygen as the oxidizer, maintaining a reaction temperature of 50°C, and allowing the reaction to proceed for 1 h
