| Abstract: | The Cu/SiO 2 and Cu-ZnO/SiO 2 catalysts were prepared by impregnation method. The effect of contents of copper and zinc oxide on the structure and property of catalysts and the activity of these catalysts on the dehydrogenation of 2-butanol and the selectivity for MEK were studied. These catalysts were characterized by means of XRD and TPR. The results indicated that the high dispersing metallic copper was the main active sites in this reaction, ZnO could disperse and stable copper species. Some interaction between copper and zinc oxide would lead to the increasing of condensation product. |
