- •
CO2 desorption conditions are optimized for energy-saving purposes.
- •
Up to 15 reuse cycles are performed in selected “mild” desorption conditions.
- •
Amine-silica CO2 adsorbents are recycled by calcination and re-functionalization.
- •
Recycled PEI samples show no changes in silica structure or amine efficiency.
- •
Grafted adsorbents display significant changes in both properties.
