At first, the 5%Fe10%Mo /γ-Al2O3 extruded catalyst was prepared by incipient wetness impregnation technique. The FeMo/γ-Al2O3 extruded catalyst was analyzed by N2-adsorption/desorption (BET), X-Ray Diffraction Inductively (XRD), Scanning Electron Microscopy (SEM), NH3-Temperature Programmed Desorption (NH3-TPD) and Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The ODS activity tests of the FeMo/γ-Al2O3 extruded catalyst was investigated by the ODS setup with light oil naphtha as feed with 250 ppm total sulfur. In order to reach the desired ODS operating conditions, different quantities of oxidant, catalyst, time and temperature of the ODS tests were examined with ODS setup and the total sulfur of each tests were recorded by Rigaku apparatus. The best ODS operating conditions was 1mL H2O2 as an oxidant, 1g FeMo/γ-Al2O3 extruded catalyst, 100 min and 50 ℃. The total sulfur of light oil naphtha reached to 45 from 250 ppm by this catalyst and ODS process UR - https://www.physchemres.org/article_150962.html L1 - https://www.physchemres.org/article_150962_d0e0b8c68d89ee6eb2222a1fec55d2a0.pdf ER -
