| 摘 要： | 研究了氧化镁负载镍、铁、钴、锰、钼、铜和锡等金属催化剂在乙醇水蒸气重整反应的性能，结果表明在650℃，101．3kpa条件下，所有催化剂的活性都较高，乙醇接近完全转化，而对氢的选择性顺序为：Ni〉Co〉Sn〉Cu〉Fe〉Mo〉Mn。除镍的选择性是随温度上升之外，其他催化剂的选择性都随温度变化有个最佳值。镍催化剂的TPR和XRD表征表明，催化剂中存在3种形态的镍。

| Abstract: | A series metal Ni,Co,Sn,Cu,Fe,Mo,Mn loaded on MgO was investigated for ethanol steam reforming reaction.Comparison was made to the metal catalysts supported on MgO.The catalytic activity was evaluated at the conditions of T=650oC,LHSV=5.0h-1,H2O/EtOH ratio=8 and atmosphere pressure.The conversion of ethanol was nearly 100%,while the selectivity to hydrogen differed greatly and followed the order Ni > Co> Sn >Cu>Fe>Mo> Mn.Experimental results showed that Ni/Mgo is superior among the catalysts,especially in t... |
