| 摘 要： | 研究了蛋壳型、蛋白型、蛋黄型和均匀型Ｐｄ／Ａｌ２Ｏ３催化剂和层状分布的ＰｄＰｔ，Ｐｄ－Ｃｏ，Ｐｄ－Ｎｉ双金属催化剂的ＴＰＲ特性。发现金属的分布对ＴＰＲ谱有影响，双金属催化剂的ＴＰＲ谱与两个单金属催化剂的ＴＰＲ谱各不相同。苯加氢反应结果表明，内层型Ｐｄ／Ａｌ２Ｏ３的活性高于壳型，添加第二组分金属对催化活性和抗硫活性有影响。

| Abstract: | The TPR spectra of differently distributing Pd/Al_2O_3, Pd-Pt/Al_2O_3, Pd-Co/Al_2Q_3 Pd-Ni/Al_2O_3 have been investigated, The metal distribution affects the TPR properties of Pd/Al_2O_3 and the specdtra of bimetal catalysts are different from those of each monometal catalysts.The catalytic activities of Pd/Al_2O_3 and Pd-bimetal catalysts for the hydrogenation of benzene also have been investigated. The activities of inner-layer typer Pd catalysts are superior to that of shell catalysts. Adding the second metal changes the catalytic activity and antisuffur property. |
