摘要: 用Ru改性的Ru-Co-Mo/Al2O3对噻吩加氢脱硫的催化性能进行了考察。结果表明,与Co-Mo/Al2O3相比,Ru-Co-Mo/Al2O3的加氢脱硫活性增高。通过CO、NO吸附的红外光谱实验证实,由于Ru的加入,吸附在Co和Mo中心上的特征谱带向低波数移动,且峰强度增强,这些结果提出了在硫化态Ru-Co-Mo/Al2O3上,Ru中心的部分d电子转移到Co、Mo中心的周围或由于Ru的存在促进了Co、Mo中心的还原。

Abstract: Catalytic performance of Ru-Co-Mo/Al2O3and Co-Mo/Al2O3catalysts in thiophene conversion as a model reaction of hydrodesulfurization has been performed, and it is shown that the conversion of thiophene on Ru-Co-Mo/Al2O3catalyst is 2 times of that/on Co-Mo/Al2O3.The infrared adsorption of COand NOon the catalysts reveals that the frequencies of COand NOadsorbed on Co, Mo sites of Ru-Co-Mo/Al2O3were shifted to low wavenumbers and their intensities were increased, in contrast to those on Co-Mo/Al2O3catalyst. It is suggested that some d electrons of ruthenium in Ru-Co-Mo/Al2Os were transferred into Co, Mo sites, leading to an increase of COand NOadsorption abilities.
