| 摘 要： | 本文采用ＸＲＤ，ＴＰＲ和以Ｈ２，ＣＯ为探针分子的ＴＰＤ—ＭＳ，ＴＰＳＲ－ＭＳ技术研究了Ｎｉ－ＣＵ合金负载于氧化物ＳｉＯ２，ＭｇＯ和γ－Ａｌ２Ｏ３上的性质变化，以及对ＣＯ加氢反应性能的影响。实验结果表明，各种载体对于负载于其上的活性组分均具有良好的分散性能；ＳｉＯ２对金属相的结构和电子状态不产生影响，而γ－Ａｌ２Ｏ３和ＭｇＯ对金属相则有不同程度的影响，这种相互作用主要表现在活性组分对Ｈ２和ＣＯ吸附能力的变化和ＣＯ加氢的活性和选择性的变化上。 |

| Abstract: | The catalysts, Ni-Cu alloy supported on various oxides, were prepared by impregnation. The interaction between Ni-Cu and supports and their catalytic properties for CO hydrogenation were studied by the techniques of XRD,TPR, TPD-MS and TPSR-MS. The experiment results showed that bimetallic catalyst is influenced by acid-base property of oxides. The interaction between Ni-Cu and supports is in the order of M/MgO>M/Y-Al2O3>M/SiO2 (M=Ni-Cu). The adsorption amount and extent of H, and CO on Ni-Cu alloy and the catalytic properties for CO hydrogenation are affected by this interaction. |
| Keywords: | Ni-Cu alloy bimetallic catalyst CO hydrogenation interaction between metal and support |
