Abstract:The choice of absorbents is crucial for the chemical absorption method to capture carbon dioxide. The research progress of CO2 capture by chemical absorption method was reviewed in detail. The structure, principle and characteristics of chemical absorbents such as carbonate solution, ammonia solution, amino solution, ionic liquid, amino acid salt solution, phase change solvent and nanofluid were emphatically introduced. It was clarified that high absorption rate, high absorption capacity and low renewable energy consumption were not only the development direction of absorbers, but also the key factors to achieve low energy consumption carbon capture. On this basis, the CO2 capture by chemical absorption method was look forward, in order to provide a new idea for industrial scale efficient green carbon capture, and help realize the green cycle development under the low-carbon economy.
