Rapid Screening of Immobilized Amine CO 2 Sorbents for Steam Stability by Their Direct Contact with Liquid H 2 O
Abstract
Rapid testing of hydrophilic and hydrophobic basic immobilized amine sorbents (BIAS) for CO 2 capture stability under practical conditions was achieved by direct contact of the sorbents with flowing liquid water. Losses in both CO 2 capture capacity and amine content of sorbents after exposure to 0.5 mL min −1 of H 2 O at 25 °C for 40 min followed similar trends as losses observed after exposure to N 2 /steam (105 °C, 7 % H 2 O) for 10 h. We also found that hydrophobic TMPED helped stabilize sorbents to H 2 O, which was confirmed by DRIFTS and combined TGA‐DSC.
