Kaolin Modified with Ni and Fe as an Effective Catalyst in the Oxidative Desulfurization Process

In the current research work, the modification of kaolin clay with MoO۳, NiO and Fe۲O۳ is investigated to prepare an effective catalyst in the oxidative desulfurization process, which to ensure the preservation of its structural, morphological and surface properties from the methods of infrared spectrometer (FTIR), visible spectrometer- Ultraviolet (UV-Vis), X-ray diffraction (XRD), gas chromatography (GC), X-ray energy diffraction spectroscopy (EDS) and scanning electron microscopy (SEM) were used. The effect of various parameters including time, temperature, oxidant, catalyst amount and DBT concentration on the oxidative desulfurization process was studied using the Taguchi method using Minitab software. The results of the analysis of kaolin catalyst modified with Mo, Ni and Fe metals, activity It showed a good catalyst and also the catalyst had the ability to recover and was reused for ۶ consecutive periods.
