Synthesis and Characterization of Cobalt Ferrite / Graphene for The Removal of Sulfur from Kerosene by Oxidative Desulfurization

Abstract

In this study, a nanocomposite cobalt ferrite / graphene, CoFe2O4-G was prepared by sol-gel method, and was identified by (XRD, AFM, and SEM) techniques. The composite was used to remove sulfur from the Iraqi kerosene (Al-Doura refinery) with a concentration of 500 ppm of sulfur. Oxidative desulfurization was used in the sulfur removal from kerosene and the composite appeared to have good effectiveness in the removal of sulfur from this kerosene under various conditions (Time, temperature, O/S ratio, and catalyst weight) as it showed a high removal activity of sulfur at optimum conditions which exceed 90 %.
