Novel Solid Sorbents for Carbon Dioxide Capture
Capture and separation of carbon dioxide from large point sources is a key step in the overall CO2 sequestration process. An improvement of the separation and capture of CO2 will thus reduce the total cost required for sequestration. NETL has recently initiated a study to develop novel amine enriched solid sorbents for the capture of CO2. This concept is to prepare the solid sorbents via chemical treatment of the surface oxide of the high surface area materials with various amine compounds. Preliminary results indicate that the amine-enriched sorbents show a capability for capture/release of CO2, and the sorbents are regenerable.
