摘要
催化剂载体是负载型催化剂的重要组成部分之一,对催化剂的稳定性和性能起着至关重要的作用.本文围绕纯碳基载体催化剂和碳-无机氧化物复合载体催化剂两个方面系统介绍了碳材料在加氢脱硫催化剂中的研究进展,总结了碳基载体的种类、性质以及应用情况,详述了不同碳基载体对催化剂活性相和催化活性等方面的增益作用.最后,结合碳基载体加氢脱硫催化剂的研究现况,展望了碳基载体未来的研究方向:一方面可聚焦设计开发新型碳基载体,拓展可制备复合载体的碳材料类型,充分发挥碳材料的形貌结构优势;另一方面应深入考察碳基载体的孔隙结构和形貌结构等性质对催化剂活性组分以及催化剂催化性能的影响,并进一步解析不同类型碳基载体制备的加氢催化剂上的加氢脱硫反应机理.
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.
