Abstract
For different separation applications of CO 2 and N 2, pure and mixture adsorption isotherms of these gases on silicalite adsorbent were determined experimentally. Constant volume and concentration pulse chromatographic techniques were used for the determination of pure and binary adsorption behavior, respectively. Pure component isotherms were determined up to 5 bar pressure for the temperature range (40 to 100) °C. Binary adsorption behavior for CO 2 and N 2 mixtures, covering the whole concentration range, were determined experimentally for a total pressure of 1 bar for the same temperature range. The applicability of different pure adsorption isotherm models was discussed for the pure isotherms, and ideal separation factors were determined. For the mixture adsorption isotherms, three binary concentration pulse methods, HT−CPM (Harlick and Tezel−Concentration Pulse Method), MTT−CPM (Modified Triebe and Tezel−Concentration Pulse Method), and MVV−CPM (Modified Van der Vlist and Van der Meijden−Concentration Pulse Method) were considered, and HT−CPM was found to be the most applicable one for this particular system. The experimental binary isotherms were compared to the predicted ones by using different binary adsorption models for this system. The results obtained showed that silicalite is a promising adsorbent for the separation of CO 2 and N 2 .

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
