“…Figure 1 shows the HDS activities of C-R Pt/Al-PILM catalysts prepared by various Pt precursors. The HDS activities of Pt/Al-PILM catalysts were remarkably changed by the kind of Pt precursor and the order of HDS activities of these catalysts was Pt( 6 . The HDS activity of Pt/Al-PILM catalyst prepared by Pt(C 5 H 7 O 2 ) 2 was higher than that of sulfided CoMo/Al 2 O 3 HDS catalyst.…”

“…Recently, the development of highly active HDS catalysts, which exhibit higher activity than commercial CoMo/Al 2 O 3 HDS catalyst, have been claimed in the petroleum industry to prevent the acid rain and deactivation of automotive exhaust catalysts [3][4][5]. Fuel consumption and carbon dioxide (CO 2 ) emission of diesel vehicle are superior to those of gasoline vehicle [6]. However, the formation of nitrogen oxide (NO X ) and particulate matter (PM) emission by diesel engine are larger than those by gasoline engine.…”

Effect of Pt precursor and pretreatment on hydrodesulfurization (HDS) activity of Pt/Al-PILM catalyst was examined to prepare highly active Pt-supported HDS catalyst. The order of HDS activities of Pt/aluminapillared clay montmorillonite (Al-PILM) catalysts prepared by various Pt precursors was Pt (C 5 6 . This order was in accordance with that of Pt dispersion. Thus, high Pt dispersion is essential factor to prepare highly active Pt/Al-PILM catalyst for HDS reaction. On the other hand, the effect of pretreatment on the HDS activities of Pt/Al-PILM catalysts prepared by various Pt precursors was also evaluated. The UC-TPS Pt/Al-PILM catalyst showed the highest HDS activity among various pretreated Pt/Al-PILM catalysts, in which uncalcined catalyst was sulfided by temperature programmed sulfidation (TPS). We assumed that high HDS activity of UC-TPS Pt/Al-PILM catalyst is caused by partly sulfided Pt particle with high dispersion. It is concluded that the highly active Pt/Al-PILM catalyst for the HDS reaction could be prepared by using Pt(C 5 H 7 O 2 ) 2 as a precursor and UC-TPS treatment.

The catalytic performances of noble metals (Pt, Rh, Pd, Ru) supported on mesoporous silica MCM-41 were investigated for the hydrodesulfurization (HDS) of benzothiophene (BT). The order of HDS activities of noble metal/MCM-41 catalysts was Pt＞Rh＞Pd≫Ru. Pt/MCM-41 catalyst showed high HDS activity, which was higher than that of commercial CoMo/Al2O3 catalyst. The supported noble metal catalysts were characterized by TEM, XRD, hydrogen adsorption and benzene hydrogenation. The order of dispersion of noble metal on MCM-41 was Rh＞Pt＞Pd＞Ru, which was not the same as that of HDS activities. On the other hand, the order of the activities of noble metal/MCM-41 catalysts for benzene hydrogenation was Pt＞Rh＞Pd＞Ru. The hydrogenation activity of Pt/MCM-41 catalyst was regenerated after H2S treatment, but the activities of other cat alysts were not regenerated. Thus, high hydrogenation activity and sulfur tolerance are important factors to pre pare highly active noble metal/MCM-41 catalysts. Pt/MCM-41 catalyst showed remarkably high and stable ac tivity for the HDS of BT, but Pt/SiO2 catalyst, with similar Pt dispersion on MCM-41, showed low activity which decreased with time on stream. Since MCM-41 showed higher acidity than SiO2, hydrogenation activity and sul fur tolerance of Pt/MCM-41 catalyst were higher than those of Pt/SiO2 catalyst. The results of FT-IR analysis indicated that the strength of interaction between BT and MCM-41 was stronger than that of SiO2, suggesting that both acid sites of MCM-41 and Pt particles in the Pt/MCM-41 catalyst act as active sites for the HDS of BT. Furthermore, FT-IR spectra of BT adsorbed on Pt/MCM-41 revealed that BT interacts with the silanol group on the MCM-41 surface rather than the Pt surface. Therefore, we concluded that the high HDS activity of Pt/ MCM-41 catalyst could be attributed to the high hydrogenation activity of Pt and the acidity of the support.
