High Surface Area Modified Resins for Carbon Dioxide Capture

Carbon dioxide (CO2) removal is essential to maintaining a breathable atmosphere inside closed systems such as that in a Navy submarine. However, current systems use corrosive materials, are energy intensive, prone to complications, and have relatively short lifetimes. Space constraints within these environments call for a maximization of the amount of CO2 to be captured for a given volume. Thus, the Navy is seeking advanced, affordable CO2 capture technology and materials to fit within, at most, the same volume as current systems. Lynntech has developed a safe and novel solution to address the above concerns by creating a regenerable scrubber based off high surface area functional materials. Lynntech will further development efforts by improving capture through synthetic modification and maximization of capture potential in a typical submarine environment. In the Phase I, Lynntech will synthesize materials, evaluate their capture potential at submarine CO2 concentrations, and tune materials to capture the maximum amount of CO2 at those concentrations. Furthermore, the regenerability of the sorbent will be optimized, with development of optimal regeneration processes for sustained use and reuse. The materials and methods that best meet the needs of the Navy will be recommended for further development.
