Kinetics and mechanism of low‐concentration CO<sub>2</sub> adsorption on solid amine in a humid confined space
Bibliographic record
Abstract
Abstract The kinetics and mechanism of low‐concentration CO 2 adsorption on a solid‐supported polyethylenimine (PEI) adsorbent in a humid confined space were investigated, where the content of CO 2 was about 0.4 % (v). A flow system, equipped with a dew point meter and IR gas analyzer connected in series for online measurement, was developed and the co‐adsorption performance of CO 2 and H 2 O was analyzed. It was found that the H 2 O adsorption capacity and activation energy were not significantly changed when 0.4 % (v) CO 2 was applied in the co‐adsorption process, indicating that the effect of dilute CO 2 could be neglected. However, the CO 2 adsorption capacity increased with the assistance of H 2 O, and then it decreased slightly when the H 2 O content in air flow was above 1.56 % (v). This implied that the adsorption activation energy of CO 2 could be significantly reduced due to the existence of H 2 O in air flow. The direct formation of bicarbonate on the supported PEI adsorbent was favoured for the co‐adsorption process of CO 2 and H 2 O.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
