CATALYST FOR BURNING CARBON-CONTAINING SUBSTANCE, PROCESS FOR PRODUCTION OF THE CATALYST, MATERIAL HAVING CATALYST CARRIED THEREON, AND PROCESS FOR PRODUCTION OF THE MATERIAL

摘要

A carbon-based combustion catalyst is obtained by performing a burning step of burning sodalite at a temperature of 600 °C or more. Alternatively, a carbon-based combustion catalyst is obtained by performing the following mixing step, drying step, and burning step. In the mixing step, aluminosilicate (sodalite), and an alkali metal source, and/or an alkaline earth metal source are mixed in water to obtain a liquid mixture. In the drying step, the liquid mixture is heated to evaporate the water, thereby obtaining a solid. In the burning step, the solid is burned at a temperature of 600 °C or more. The thus-obtained catalyst can cause carbon-based material to be stably burned and removed at a low temperature for a long time.
