| 本文综述了含硫化合物在体相、负载以及改性的过渡金属磷化物催化剂上的加氢脱硫机理研究，讨论了催化剂的结构-活性之间的关系，以及不同类型磷化物对含硫化合物在催化剂上的反应路径的影响。同时，一些研究中不同阶段速率常数的计算让我们对反应步骤有了更深入的认识，并对含硫化合物在磷化物催化剂上的反应动力学和反应网络有了进一步了解，为新型磷化物深度加氢脱硫催化剂的开发和应用提供理论基础，具有重要的学术价值和普遍指导意义。 |
| 英文摘要: |
| In this paper the mechanism of the hydrodesulfurization（HDS） reaction of sulfur-containing compounds over bulk transition metal phosphide catalysts, supported transition metal phosphide catalysts, and modified transition metal phosphide catalysts were reviewed. The structure-activity relationships of catalysts, the influence of different types of catalysts on the reaction paths of sulfur-containing compounds over catalysts were also discussed in detail. The calculation of rate constant of different HDS steps over phosphide catalyst led to a better understanding of HDS reaction steps. These results can also help us to understand the reaction kinetics and reaction network of sulfur-containing compounds over phosphide catalysts, which offers an important academic value and general guiding significance for the development and application of new-style deep HDS catalyst. |
