Invention Reference Number
Encapsulating CO2-reactive liquids, such as amines, task-specific ionic liquids (TSILs) and deep eutectic solvents, into protective polymer shells offers an innovative way to improve carbon capture. This approach enhances absorption efficiency, preserves the solvents, and enables efficient regeneration, making it a practical solution for removing and reducing carbon emissions entering the atmosphere to reverse the effects of greenhouse gas emissions.
Description
The process involves coating CO2-absorbing liquids with a polymer composite shell to create flowable powdered capsules. These powdered capsules capture CO2 more efficiently by increasing the surface area available for contact, thus reducing mass transport and diffusion limitations and selectively allowing CO2 through while rejecting other gases like water and oxygen. This encapsulation not only prevents solvent loss but also simplifies regeneration, allowing the materials to be reused without degradation as well as increasing the energy efficiency needed. The result is a more reliable, cost-effective, and environmentally friendly carbon capture method.
Benefits
Improved Efficiency: Faster and more effective CO2 absorption and desorption compared to traditional liquids.
Solvent Preservation: Protects the liquid from evaporation and decomposition, ensuring long-term use.
Easy Handling: Converts liquids into flowable powders for ease of handling flexible application in various systems.
Cost-Effective: Reduces energy needed for regeneration and avoids material loss.
Versatile Use: Works with different solvents and can be adapted to multiple systems and devices.
Applications and Industries
Ideal for capturing CO2 from industrial emissions or directly from the air.
Can be applied to air filtration systems to improve indoor air quality and utilize in place distributed HVAC air handling systems.
Used in power plants and manufacturing to reduce carbon footprints.
