To reduce the concentration of CO? in the atmosphere, it generally falls into two categories: reducing carbon emissions and increasing carbon absorption. The demand for carbon dioxide capture agents is concentrated in industries with high CO? emissions, such as fossil fuel power plants (e.g., coal-fired power plants), waste-to-energy power plants, steel, and non-ferrous metals like aluminum.

Carbon dioxide capture agents are prepared through pelletizing and rolling processes, exhibiting high selectivity for carbon dioxide in multi-component gas mixtures. Compared to existing methods such as solvent absorption and membrane separation for CO? capture, they offer advantages including simpler processes, lower energy consumption, ease of regeneration, and environmental friendliness.
