Al2O3基石油加氢脱硫催化剂研究现状与进展

摘要

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 re-viewed 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 Al2O3as carrier catalysts,and offers a prospective presentation on the potential research directions for im-proving the performance of Al2O3-based HDS catalysts.%综述了以三氧化二铝(Al2O3)为载体,负载 Mo、Ni单一组元和 Mo-Ni-W等复合组元,用于炼制石油加氢脱硫的催化剂的国内外研究现状与进展.全面总结了传统的浸渍法、混捏法、共沉淀法、离子交换法以及新型的微波-超声波法等催化剂合成方法,对 Al2O3基催化剂的加氢脱硫性能进行了讨论,着重对催化剂合成过程中载体、活性组分、助剂(P、F、B等)和 pH 值对催化剂性能的影响进行了概述,在此基础上总结了 Al2O3基加氢脱硫催化剂的不足之处,并展望了此类催化剂的发展方向与研究前景.
