ZnO在CuO基甲醇合成催化剂还原过程中的作用(英)

Role of ZnO in Reduction Process of CuO Based Catalyst for Methanol Synthesis

用一步并流共沉淀法制备了一系列具有不同组成的ＣｕＯ基样品，并测试了它们在合成甲醇反应中的活性。利用ＴＧＤＴＧ手段，对各ＣｕＯ基样品的还原过程进行了考察，结果表明，ＺｎＯ组分对催化剂ＣｕＯＺｎＯＡｌ２Ｏ３的还原行为有重要影响。依据ＣｏａｔｓＲｅｄｆｅｒｎ

A series of CuO based samples with different compositions have been prepared and their catalytic activities for methanol synthesis have been tested.By means of TG DTG,the reduction process of CuO based Samples were investigated.The results indicated that the ZnO component affected the reduction behavior of the CuO ZnO Al 2O 3 sample significantly.By using Coats Redfern,the kinetic parameters of reduction of the CuO based samples were obtained.
