Abstract:
Provided is a method for reducing carbon dioxide concentration in a gas for treatment containing carbon dioxide, such as combustion exhaust gases from thermal power plants used by power companies, various factories, business facilities, waste disposal sites, and the like, wherein coal, biomass, mixed fuel, or the like, serve as a fuel. The method for reducing carbon dioxide concentration in the gas for treatment includes a contacting step of bringing into contact with the gas for treatment containing carbon dioxide a dispersion solution containing biomass incineration ash, to yield a carbon dioxide-adsorbed ash wherein the biomass incineration ash has adsorbed the carbon dioxide contained in the gas for treatment.
