Abstract

In a study on methanol decomposition over Cu based catalysts, it was found that the catalyst deactivation rate can be drastically reduced by adding CO<inf>2</inf> in the feed. The enhancement of the catalyst stability was attributed to the retardation of catalyst sintering and carbon deposit on catalysts. However, the presence of CO<inf>2</inf> did not alter the product distribution and initial catalyst activity. The results suggest a novel use of CO<inf>2</inf> in methanol decomposition and a simple and efficient method to increase the stability of copper based catalysts.
