| 摘 要： | 以两种商用Al2O3为载体,制备了汽油选择性加氢脱硫催化剂Co-Mo/Al2O3,并采用红外光谱、X射线衍射、N2吸附-脱附、透射电镜、扫描透射-能谱和X射线光电子能谱等手段系统研究了载体物化性质对催化剂活性相形成的影响.结果表明,表面羟基数量少和结晶程度高的载体与活性金属间相互作用减弱,促进了Mo物种的硫化还原,使MoS2片晶的尺寸和层数增加,且其硫化态催化剂上CoMoS活性位更多,CoMoS/MoS2比更大,因而显著提高了相应Co-Mo催化剂加氢脱硫活性和选择性.

| Abstract: | Two different commercial alumina supports were used for the preparation of selective hydrodesulfurization(HDS) catalysts Co-Mo/Al2O3. The effect of support properties on the HDS activity and selectivity of the corresponding Co-Mo catalysts were studied by X-ray diffraction,Fourier transform infrared spectroscopy,transmission electron microscopy,scanning transmission electron microscopy-energy dispersive X-ray spectroscopy,and X-ray photoelectron spectroscopy. The HDS activity and selectivity were measured u... |
