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。
In this paper, the mechanism of hydrodesulfurization of sulfur-containing compounds on bulk, supported and modified transition metal phosphide catalysts is reviewed. The relationship between the structure-activity of the catalysts and the effects of different types of phosphides on sulfur compounds in Influence of the reaction path on the catalyst. At the same time, the calculation of the rate constants at different stages in some studies gave us a deeper understanding of the reaction steps and further understanding of the reaction kinetics and reaction networks of the sulfur-containing compounds on the phosphide catalyst as the basis for the new phosphide depth Hydrodesulfurization catalyst development and application of theoretical basis, has important academic value and general guiding significance.
