Abstract
The feasibility of using triamine-grafted pore-expanded mesoporous MCM-41 silica (TRI-PE-MCM-41) as a potential adsorbent for simultaneous removal of CO 2 and H 2 S was investigated. Adsorption isotherms of CO 2 and H 2 S were measured at different temperatures, whereas adsorption at low H 2 S concentrations from 700 to 10000 ppm with balance CO 2 was studied at 298 K. It was found that both CO 2 and H 2 S adsorb and the selectively toward H 2 S versus CO 2 decreases at an increasing H 2 S concentration. Because TRI-PE-MCM-41 hardly adsorbs any of the common gases, such as CH 4, H 2, N 2, O 2, and CO, it was inferred that this material may be suitable for the purification of a variety of gas streams containing CO 2 and H 2 S. These findings lay the ground for the development of a single-stage process for the removal of CO 2 and H 2 S from biogas, using amine-supported PE-MCM-41.

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 it
