Ni2P catalysts supported on SiO2 and SBA-15 were successfully prepared by temperature-programmed reduction (TPR), and the effect of Ni2P dispersion on the 4,6-dimethyldibenzothiophene hydrodesulfuriza...
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 activit...
The present study evaluated 129Xe NMR spectroscopy for the analysis of Co-Mo/Al2O3 hydrodesulfurization catalyst. This study also reconsidered the conventional interpretation of 129Xe NMR spectroscop...
Hydrodesulfurization (HDS) of thiophene over silica-modified alumina-supported platinum (Pt/SiO2-Al2O3) catalysts was examined. The HDS activity of a Pt/Al2O3 catalyst was enhanced by silica modifica...
The differences between MoS2, CoMoS and NiMoS HDS catalysts supported on γ-alumina and high SSA titania are investigated based on the results of [35S]DBT HDS experiments. Previous studies of MoS2 and ...
Resid hydrodesulfurization catalyst was regenerated after commercial operation and the effect of vanadium accumulation during resid hydrotreating reaction on the following catalyst regeneration was i...
The effect of sulfidation on 129Xe NMR spectra of Co-Mo/Al2O3 hydrodesulfurization catalysts was investigated. Before sulfidation, catalysts containing cobalt such as Co/Al2O3 and Co-Mo/Al2O3 showed ...
Hydrodesulfurization (HDS) of catalytic cracked gasoline (CCG) over Co-Mo/γ-Al2O3 catalyst was investigated to clarify the important factors for deep HDS of CCG containing 229 ppm sulfur and 30.4 vol...
The catalytic activities and properties of noble metals (Pt, Pd, Rh, Ru) supported on silica gel (SiO2) and alumina-modified silica gel (Al2O3-SiO2) were investigated for the hydrodesulfurization of ...
Effects of the carrier characteristics were studied on the catalytic properties of Pt-Pd-supported USY zeolites in the hydrogenation of tetralin and the hydrodesulfurization of 4,6-dimethyldibenzothio...
Mo catalysts were prepared by impregnation of titania synthesized by the pH swing method which provides a TiO2 carrier with a high specific surface area (134 m2·g−1) and excellent mechanical pr...
129Xe NMR (nuclear magnetic resonance), a useful analytical tool for the investigation of zeolite pores, was evaluated as a novel technique for the analysis of active sites on Mo/Al2O3 hydrodesulfuri...
The effect of cobalt addition on Mo/Al2O3 hydrodesulfurization catalyst was investigated by 129Xe NMR. Both the amount of adsorbed xenon and the peak width of 129Xe NMR were almost constant at variou...
The catalytic precursors of alumina-supported molybdenum dithiocarbamate (Mo-DTC) and molybdenum dithiophosphate (Mo-DTP) were assessed as catalysts for hydrodesulfurizastion (HDS). The effect of the...
A new additive approach using polyethylene glycol (PEG) as a water soluble organic compound was proposed to improve hydrodesulfurization activity over CoO-MoO3/Al2O3 catalyst. The addition of PEG to ...
