Characteristics of ion exchange resins: 

1. High specific surface area: Provides a large number of adsorption sites, which is conducive carbon dioxide adsorption. 

2. Adjustable ion exchange capacity: The adsorption capacity for carbon dioxide can be adjusted by changing the chemical structure and synthesis conditions of the. The adsorption rate of carbon dioxide can reach over 95%. 

3. Good chemical stability and mechanical strength: Can work stably under different environmental, with a long service life. 

4. Easy to regenerate: Compared with other adsorbents, ion exchange resins are relatively easy to regenerate. They can regenerated by heating, depressurization, or using specific eluents, thereby reducing the operating costs of direct air capture systems.

Application of ion exchange resins in carbon capture, utilization and storage (CCUS): 

Industrial process carbon capture In post-combustion capture, ion exchange resins can be used to capture carbon dioxide from flue gas. In some industrial processes, such as ammonia synthesis and oil refining, large of carbon dioxide emissions are also produced. Ion exchange resins can be used for carbon capture in these industrial processes to achieve recovery and utilization of carbon dioxide. For, in the process of ammonia synthesis, ion exchange resins can be used to adsorb and separate carbon dioxide, improving the efficiency of ammonia synthesis and reducing carbon.

Application of ion exchange resins in direct air capture (DAC): 

Direct air capture is a technology that directly captures carbon dioxide from the air, and has broad application prospects. Ion exchange resins are used as adsorbents in direct air capture to achieve efficient capture of low-concentration carbon dioxide in the air.
