Capture of CO<sub>2</sub> from combustion gases in a fluidized bed of CaO
Bibliographic record
Abstract
Abstract Experiments in a pilot‐scale fluidized‐bed reactor have been carried out to investigate the carbonation reaction of CaO, as a potential method for CO2 capture from combustion flue gases at high‐temperatures. Results show that CO2 capture efficiencies are very high, while there is a sufficient fraction of CaO in the bed reacting in the fast reaction regime. The total capture capacity of the bed decays with the number of carbonation‐calcination cycles. The experimental CO2 concentration profiles measured inside the bed during the fast reaction period are interpreted with the KL fluid bed model, by supplying information on sorbent deactivation from laboratory tests. It is concluded that a fluidized bed of CaO can be a suitable reactor to achieve very effective CO2 capture efficiencies from a combustion flue gas. © 2004 American Institute of Chemical Engineers AIChE J, 50:1614–1622, 2004

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
