为了研究活性组分的负载对催化剂加氢脱硫性能的影响,设计并制备了Co/Si/Mo/Ni/Al₂O₃多元复合催化剂。通过固定床催化剂评价装置对其进行二苯并噻吩加氢脱硫反应活性评价,并利用X射线衍射仪(XRD)、N₂吸附测试仪、X射线光电子能谱仪(XPS)、扫描电子显微镜(SEM)和Mapping等分析测试手段对催化剂进行表征。结果表明,复合催化剂具有优良的加氢脱硫性能,当活性组分负载量为(0.5% Co)/(1.5% Si)/(3.0% Mo)/(10.0% Ni)/Al₂O₃时,其加氢脱硫性能最高可达到96.1%。

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.
