Outline of Final Research Achievements

Monolithic catalysts are widely used in the abatement of pollutants, especially automotive pollution control. In order to understand the catalytic reaction and to obtain the knowledge leading to the catalyst design, probing what happens inside the monolithic catalyst is important issue. The gas composition in the gas flow direction for CO oxidation over monolithic CeO2-ZrO2 was analyzed by using prototype gas sampling apparatus, which was designed and developed in this study. CO conversion was found to be gradually increased in the gas flow direction at low reaction temperature, while CO oxidation was almost completely finished at the middle of monolithic catalyst at higher temperatures. The effectiveness of this method was confirmed.
