Development of highly active noble metal phosphide catalyst for Production of clean fuel with low sulfur content

本研究旨在探讨贵金属磷化物（NMXPY）的形成及其脱硫活性，以开发新型高活性加氢处理催化剂。结果总结如下1.还原后，在每种加磷贵金属（P-NM）催化剂中观察到NMxPy物种的形成。SiO_2、TiO_2和Al_2O_3是Rh-P催化剂的合适载体。3.以乙酰丙酮配合物为载体制备的Pd-P催化剂活性高于以氯化物为载体制备的Pd-P催化剂。4. NM-P催化剂的最佳P负载量为：Rh-P 1.5- 2.2wt%，Pd-P 0.8- 1.5wt%，Ru-P 1.5wt%。

In this study, we examined that formation of noble metal phosphides (NMXPY) and its desulfurization activity to develop highly active new hydrotreating catalyst. Summary of the results are as follows1.Formation of NMxPy species were observed in each P-added noble metal (P-NM) catalysts after reduction. In particular, Rh-P catalyst showed the highest activity among NM-P catalysts.2.SiO_2, TiO_2, and Al_20_3 were suitable supports for Rh-P catalyst. Furthermore, the Rh-P supported on Ti-modified SiO_2 showed higher activity than on these supports.3.Pd-P catalyst prepared from acetylacetonate complex has higher activity than that from chloride.4.The optimal P loading for NM-P catalysts are as follows ; Rh-P 1.5-2.2wt%, Pd-P 0.8-1.5 wt%, Ru-P 1.5wt%.
