The objective of this collaborative effort was for RTI to develop an intimate understanding of Pennsylvania State University's Molecular Basket Sorbent (MBS) and evaluate the potential for developing a solid sorbent-based CO2 capture process using the MBS materials as a platform chemistry. Testing performed by RTI was focused on evaluating the effect of process variables on dynamic CO2 loading capacity, rate of CO2 capture and regeneration, ability to achieve high CO2 removal efficiencies, and the ability to regenerate in the presence of CO2. In addition, extended multi-cycle absorption-regeneration experiments were completed using a high-fidelity flue gas composition containing CO2, H2O, O2, SO2, and N2. The MBS material exhibited very promising performance characteristics including CO2 loading capacities > 16 wt% CO2, fast absorption kinetics resulting in the ability to achieve 100% CO2 removal at GHSVs > 5,000 h-1, and near complete loading prior to CO2 breakthrough.
