Abstract:
The influence of thermal and hydrothermal treatments and reduction processes on the activity of CuO-ZnO catalysts was studied. Temperature-programmed reduction (TPR) was used in the study of catalyst activation with different reduction mixtures. A mixture of H2 and N2 in the range of 500 to 573 K was the most effective reducing agent. High temperature, water vapor and a high partial pressure of hydrogen enhance Cu sintering and Cu-Zn alloy formation with a decrease in catalytic activity. XRD analysis of reactivated catalysts showed that their deactivation can be related to the formation of surface spinel species. Reoxidation at 623 K and subsequent reduction of the aged catalyst led to metal redispersion but not catalyst regeneration. © 1997 Elsevier Science B.V. All rights reserved.
