| Research Abstract |
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 follows
1.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%.
