Abstract
Solid amine sorbents have emerged as a promising technology for carbon capture due to their ability to selectively adsorb CO2 from gas streams through reversible reactions. This review discusses the principles, advantages, and applications of solid amine sorbents for carbon capture. Solid amines like monoethanolamine (MEA) and diethanolamine (DEA) can be incorporated into various materials like pellets and membranes, offering flexibility for different capture systems. Key benefits of solid amine sorbents include high CO2 selectivity, stability, multiple regeneration cycles, and potential uses in various industries like power plants, cement, steel, and gas processing. However, challenges remain in scaling up production while optimizing performance and cost-effectiveness. Promising research directions include developing advanced solid amine materials, integrating sorbents with other technologies, and exploring new applications beyond carbon capture. Overall, solid amine sorbents provide a versatile carbon capture approach that can be tailored based on the source and concentration of CO2. With continued research and development, solid amine sorbents have the potential to play a key role in reducing greenhouse gas emissions across multiple industries.
