Abstract: This review focuses on the research advances in hydrodesulfurization catalysts supported on carbon-based materials such as activated carbon,carbon nanotubes,mesoporous carbon and graphene.Compared with conventional Al2O3-supported catalysts,carbon-supported catalysts have large specific surface area,good dispersion of active metals and weak interaction between active metal and carbon surface,which is conducive to the formation of type Ⅱ active phases with high activity.Taking dibenzothiophene,4,6-dimethyldibenzothiophene and other sulfur-containing organic compounds as the treatment objects,carbon-supported hydrodesulfurization catalysts generally have higher hydrodesulfurization catalytic performance than those catalysts supported on Al2O3.In order to meet the demand of industrial applications,the preparation cost of carbon-supported hydrodesulfurization catalysts needs to be reduced.And the pore structures and surface properties of carbon-supported hydrodesulfurization catalysts should be optimized and modified according to the needs of catalytic system.Furthermore,it is necessary to strengthen the research on the mechanism and kinetics of hydrodesulfurization reaction,to promote the progress in hydrodesulfurization catalyst and process technology.
