Abstract

Solid amine sorbents having adequate particle size with high CO₂ adsorption capacity were successfully prepared using poly(ethylenimine) (PEI) as the amine and mesoporous poly(methyl methacrylate) (PMMA) beads as the support. The PEI-impregnated PMMA-supported sorbent exhibited CO₂ adsorption capacity up to 4.26 mmol/g with PMMA-55 at 75 °C in pure CO ₂ gas flow. The effect of the temperature on the adsorption capacity of PMMA-55 was investigated, and the maximum adsorption capacity was obtained at 50 °C with a CO₂ exposure time of 180 min, different from the tendency of most silica-supported sorbents. The effect of surfactant addition on the adsorption performance of PMMA-supported sorbents differed from those of silica-supported sorbents because of the different surface characteristics between PMMA and silica. Adsorption/desorption cycling was also performed to examine the suitability of the amine sorbent for potential application.
