Characterization of Co-Mo/Al2O3 Hydrodesulfurization Catalyst by 129Xe NMR Spectroscopy
129Xe NMR Cobalt molybdenum catalyst Sulfidation Co-Mo-S phase
2009/8/4
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...
Application of 129Xe NMR Spectroscopy to Analysis of Co-Mo/Al2O3 Hydrodesulfurization Catalyst —Effect of Sulfidation on 129Xe NMR Spectra—
129Xe NMR Cobalt molybdenum catalyst Sulfidation Peak broadening
2009/7/28
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 ...

129Xe NMR Molybdenum alumina catalyst Molybdenum sulfide crystallite
2009/7/27
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...
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...
采用连续流动的激光诱导超极化 129Xe 为探针分子, 利用高分辨固体核磁共振技术研究了不同电子结构的金属阳离子 (Na+, Ag+, Cu2+, Cu+, Cs+) 交换的 FAU 型分子筛与超极化 129Xe 之间的相互作用. 结果表明, 超极化 129Xe 能够很灵敏地检测不同电子结构的金属离子对限阈空间中电场梯度的影响. Na+对超笼内电场梯度的影响很小, NaX 与 NaY 分子筛中...
