AI Technical Summary

Technical Problem

Existing solid carbon dioxide recovery materials lack durability and are difficult to use for extended periods.

Method used

Solid recycled materials containing iron, sodium, and crystalline carbon are used, combined with amorphous carbon and polymer binders, to form a structure with high strength and water resistance. Adsorption and desorption are achieved through the reaction of sodium ferrite with carbon dioxide.

Benefits of technology

It achieves high-efficiency carbon dioxide recovery performance and has good water resistance and strength, enabling it to be used repeatedly over a long period of time.
