Abstract

Global warming resulting from the emission of greenhouse gases, especially CO2, has become a widespread concern in the recent years. Though various CO2 capture technologies have been proposed, chemical absorption and adsorption are currently believed to be the most suitable ones for post-combustion power plants. The operation of the chemical absorption process is reviewed in this work, together with the use of absorbents, such as the ionic liquid, alkanolamines and their blended aqueous solutions. The major concerns for this technology, including CO2 capture efficiency, absorption rate, energy required in regeneration, and volume of absorber, are addressed. For adsorption, in addition to physical adsorbents, various mesoporous solid adsorbents impregnated with polyamines and grafted with aminosilanes are reviewed in this work. The major concerns for selection of adsorbent, including cost, adsorption rate, CO2 adsorption capacity, and thermal stability, are compared and discussed. More effective and less energy-consuming regeneration techniques for CO2-loaded adsorbents are also proposed. Future works for both absorption and adsorption are suggested.

  • Adsorption is one of the most promising methods for reducing atmospheric CO2, offering excellent stability, straightforward regeneration, and effective adsorption capabilities.

    “One of the most promising methods for reducing atmospheric CO2 is adsorption, which offers excellent stability, straightforward regeneration, and effective adsorption capabilities6–8.”

    From Metals incorporated agricultural waste corn Cob-based biochar used as an adsorbent for CO2 capturing (2025) · cites this paper as [7]

    The Introduction and Conclusions describe adsorption as a potential CO2-capture method and report high capacity for some amine-based adsorbents. But the paper focuses on sources such as power-plant flue gas, not removal of CO2 from ambient air. Its Regeneration Process section says effective, less energy-intensive regeneration still needs development, so it does not support calling regeneration straightforward or stability and capacity general advantages of adsorption.

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.
