Study on construction of active phase and hydrodesulfurization performance of Fe-based hydrogenation catalyst
The article provides a comprehensive overview of the research progress in iron(Fe)-based hydrodesulfurization(HDS)catalysts,offering crucial insights into the development of efficient and economical metal-based hydrogenation catalysts.Drawing upon years of research conducted by our research group in the field of Fe-based HDS catalysts,this paper systematically summarizes the evolution of Fe-based HDS catalysts,with a particular emphasis on elucidating the electronic structure modulation mechanisms of Fe-based catalysts and their subsequent impact on HDS performance.Furthermore,it delves into the analysis of the HDS reaction mechanisms of Fe-based catalysts in the presence of dibenzothiophene(DBT)and 4,6-dimethyldibenzothiophene(4,6-DMDBT),offering valuable insights into the catalytic processes.This comprehensive review serves as a roadmap for the design and development of low-cost HDS catalysts.
