Oxidative desulfurization of hydrotreated gas oil using Fe2O3 and palladium loaded over activated carbon as catalyst

Abstract

This paper describe preparation of catalysts Fe2O3/Ac and Pd/Ac by precipitation method according to the ratio cat: Ac (20:80) and evaluates their catalytic activity to remove sulfur compounds from hydrotreated gas oil. The chemical structure of the prepared catalysts were examined by X-ray diffraction (XRD) analysis, atomic absorption spectroscopy (AAS), surface area and pore volume, and thermal gravimetric analysis (TGA). X-ray fluorescence spectrometer used to determine the content of sulfur in gas oil before and after the treatment. The catalysts in this study showed an efficient removal of sulfur compounds from light gas oil reaches to more than 60%.
