Project Description

Texas A&M University has teamed with framergy™ and Advanced Clean Energy Solutions, LLC to develop and test amine-incorporated porous polymer networks (aPPNs) for low-energy selective capture of carbon dioxide (CO2) from flue gas. aPPNs are novel porous sorbents that exhibit exceptional gas uptake capacities and working capacities, with the added capability of fine tuning the CO2 selectivity through the incorporation of amine groups. These innovative materials will address many of the limiting factors in both solvent and other sorbent-based CO2 capture methods, mainly the energy required to regenerate the post-combustion CO2 capture system. The project objectives are to optimize the sorbent and process technologies to develop a scalable, highly-robust, and highly-efficient sorbent, and validate the sorbent through lab-scale testing in a fixed-bed integrated absorber and regenerator system with simulated flue gas. The goal at the end of this lab-scale evaluation is to collect all the relevant data and overcome the challenges for scaling up the best performing sorbent for future bench-scale testing in a fluidized-bed system.

Project Benefits

The outcome of this technology development effort will be new scalable materials with increased CO2 capture capacity and efficiency. The aPPN sorbents have potential to achieve high working capacity and low heat capacity leading to a decrease in capital costs and energy requirements. The optimized sorbents are anticipated to be capable of capturing 90 percent of CO2 from flue gas, achieve 95 percent purity of CO2, and reduce the energy required for sorbent regeneration to less than 10 percent penalty of total energy production from the associated power generation system.
