Preparation of Engineerable Solid Amine Beads for Efficient Carbon Dioxide Adsorption from Simulated Flue Gas
Highly engineerable solid amine beads were facilely prepared by impregnating two commercially available resins (SQD-96 and A110) with tetraethylenimine (TEPA) and polyethylenimine (Mw = 600, PEI600). The optimal loading of each resin was determined by testing the CO2 adsorption capacities at both 25 and 50 °C, showing that SQD-96 impregnated with a 0.25 mass ratio of TEPA and PEI600 (designated as 0.25TEPA/PEI600@SQD-96) exhibited the highest performance, followed by 0.10TEPA/PEI600@A110. After thorough characterization and comparison on structure, morphology, and stability, 0.25PEI600@SQD-96 was identified as the most promising candidate for cyclic CO2 adsorption from simulated flue gas in fixed beds. Thermodynamic and kinetic modeling was additionally used to calculate the adsorption heat and activation energy for this material.
