Carbon dioxide capture agent captures carbon dioxide.

To reduce the concentration of CO₂ 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 CO₂ emissions, such as fossil fuel power plants (e.g., coal-fired power plants), waste-to-energy plants, steel, non-ferrous metals like aluminum, and others.

Carbon dioxide capture agents are prepared through pelletization and exhibit high selectivity for carbon dioxide in multi-component gas mixtures. Compared to existing methods such as solvent absorption and membrane separation for CO₂ separation, they offer advantages such as simpler processes, lower energy consumption, easy regeneration, and environmental friendliness.
