Comparison by 35S Radiotracer Methods of Hydrodesulfurization Behavior for Molybdenum, Cobalt-Molybdenum and Nickel-Molybdenum Catalysts Supported on γ-Alumina and High Specific Surface Area Titania
Hydrodesulfurization Dibenzothiophene γ-Alumina High surface area titania
2009/7/28
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 ...
Hydrodenitrogenation and Hydrogenation of Aromatic Compounds over Titania Supported Cobalt Molybdenum Catalysts
Titanium dioxide support Cobalt molybdenum catalyst Hydrodesulfurization catalyst
2009/7/28
Newly developed CoMo titania catalysts for ultra-deep hydrodesulfurization (HDS) of diesel oil have higher activities for both HDS and hydrodenitrogenation (HDN), whereas the chemical hydrogen consum...
129Xe NMR Analysis of Mo/Al2O3 Hydrodesulfurization Catalyst (Part 2) Effect of Cobalt Addition
129Xe NMR Molybdenum alumina catalyst Sulfurization Cobalt addition
2009/7/24
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...
Partial Oxidation of Methane to Synthesis Gas over Oxidized Diamond Supported Catalysts—Catalytic Behavior of Nickel and Cobalt Species—
Partial oxidation Diamond Methane Synthesis gas Pulse method
2009/7/24
Characterization of nickel and cobalt catalysts supported on oxidized diamond (O-dia) in the partial oxidation of methane to synthesis gas was carried out by X-ray photoelectron spectroscopy (XPS) an...
