Abstract The research status and progress of hydrodesulfurization (HDS) catalysts with single active component (Mo and Ni) and multiple active components (Mo, Ni and W, etc.) with the aluminium oxide (Al2O3)-based single and mixed supports is reviewed from the perspective of petroleum refining. We herein introduce the traditional synthesis methods, such as impregnation method, kneading method, co-precipitation method and ion exchange method, and the newly emerged microwave-ultrasonication method, discuss the hydrodesulfurization performance of the Al2O3-based catalysts with emphasis on the summary of performance’s dependences on catalyst supports, active components, additives (P, F, and B, etc.) and pH environment. Finally, the paper points out the shortcomings of Al2O3 as carrier catalysts, and offers a prospective presentation on the potential research directions for improving the performance of Al2O3-based HDS catalysts.
