| 摘 要： | 用X光能谱定量分析了钼,钴和镍在Al_2O_3-TiO_2载体和预浸TiO_2的Al_2O_3载体上的径向浓度分布。并与Mo、Co、Ni/Al_2O_3催化剂的活性组份分布特征做了比较。实验数据表明钼、钴和镍诸组份相对富集在二氧化钛的高浓度区,证明了二氧化钛对钼、钴和镍的竞争吸附效应及其对浓度分布的影响。

| Abstract: | In present paper, the radial concentration distribution of Mo, Co and Ni on Al_2O_3 -TiO_2 support and Al_2O_3, with preimpregnated TiO_2 support has been quantita- tively determined by X-ray energy dispersive spectrometer. The results obtained have been compared with the concentration distribution of active species in the Mo, Co, Ni/Al_2O_3, hydrogenation catalyst. The experimental data have demonstrated that Mo, Co and Ni are relatively concentrated in the area with high concentration of TiO_2. And this fact has verified the competitive adsorption of Mo, Co and Ni by TiO_2 and the influence of TiO_2 on the concentration distribution of the species in the catalysts. |
