Abstract:

Support is one of the important components of supported catalyst, playing a crucial role in maintaining the stability and performance of catalyst. This paper systematically introduces the research progress of carbon materials used in hydrodesulfurization catalysts, focusing on two aspects: pure carbon-based support catalysts and carbon-inorganic oxide composite support catalysts. The types, properties and applications of carbon-based support were summarized, and the promoting effects of different carbon-based support on the active phase and catalytic activity were elaborated. Finally, based on the current research status of carbon-based support hydrodesulfurization catalysts, the future research direction of carbon-based support is prospected. On one hand, it can focus on the design and development of new carbon-based supports. It is important to diversify the types of carbon-based supports that can be used to prepare composite supports, and fully take the morphological and structural advantages of carbon materials. On the other hand, it is necessary to thoroughly investigate the effects of pore structure and morphology of carbon-based supports on the active components and catalytic performance of catalysts, and clarify the hydrodesulfurization mechanism of the catalysts with different types of carbon-based supports.
