Abstract: In order to study the effect of active component loading on the hydrodesulfurization performance of the catalyst,Co/Si/Mo/Ni/Al2O3 composite catalyst is designed and prepared.The activity of the catalyst in hydrodesulfurization of dibenzothiophene is evaluated through a fixed bed catalyst evaluation device,and the catalyst is characterized by X-ray diffraction (XRD),N2 adsorption,X-ray photoelectron spectroscopy (XPS),scanning electron microscopy (SEM) and Mapping.The results show that the composite catalyst has excellent hydrodesulfurization performance.The highest hydrodesulfurization performance can reach 96.1% when the loading amount of active component is (0.5% Co)/(1.5% Si)/(3.0% Mo)/(10.0% N)/Al2O3.
