REDUCING COMPONENT REMOVAL MATERIAL AND PRODUCTION METHOD THEREOF, AND REDUCING COMPONENT REMOVAL METHOD, GAS PURIFICATION METHOD AND GAS PURIFIER

Japanese Patent JP2023061364

A

To provide a reducing component removal material at a low production cost and with high absorption capability even in low concentration carbon dioxide with about several ppm; and to provide a reducing component removal method using the reducing component removal material, a gas purification method and a gas purifier.SOLUTION: A reducing component removal material removes a reducing component contained in raw material gas containing oxygen, and oxidation catalyst metal is supported by active alumina containing sodium. The reducing component is oxidized by bringing the raw material gas into contact with the reducing component removal material, and a reaction product by the oxidization is removed by absorption simultaneously. The oxidization and absorption removal are performed under a condition of 0-100°C, and the reducing component removal material after the absorption removal can be repeatedly used by heating it to 100-300°C for regeneration.SELECTED DRAWING: Figure 1
