| Abstract: | 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. |
