Thermal, Oxidative, and CO2-Induced Degradation of Supported Polyethylenimine Adsorbents
Abstract
This work examines the stability of polyethylenimine(PEI)-impregnated mesoporous silica for CO 2 removal over a wide range of conditions. The support used was a SBA-15 silica with platelet morphology and short pore channels (SBA-15PL). The effect of long-term exposure to different gaseous streams, including carbon-free air (CFair), simulated flue gas (SFG), and different CO 2 /O 2 /N 2 mixtures on the carbon dioxide adsorption capacity was investigated. Extensive CO 2 adsorption–desorption cycling using dry and humid streams at different adsorption and regeneration temperatures was also carried out. Based on adsorption data, as well as diffuse reflectance infrared Fourier transform (DRIFT) and 13 C CP MAS NMR measurements, it was found that PEI-modified adsorbents exhibit (i) high thermal stability at moderate temperatures, (ii) highly stable CO 2 uptake in the presence of moisture, (iii) extensive degradation in the presence of dry CO 2, particularly at high temperature, (iv) fast degradation upon exposure to CFair even at moderate temperatures, (v) excellent stability in the presence of humidified gases containing both CO 2 and O 2 .

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
