Adsorption of Binary Mixtures of Propane−Propylene in Carbon Molecular Sieve 4A
Bibliographic record
Abstract
We studied binary adsorption equilibrium and kinetics of propane and propylene in carbon molecular sieve 4A (Takeda Corp., Tokyo, Japan). Adsorption equilibrium was measured at 373 K with a manometric−chromatographic unit at two different total pressures: 47 and 250 kPa. Equilibrium of the binary mixture was well predicted with the multicomponent multisite model equation based on pure gas data. The integral thermodynamic consistency test was applied to the set of data. Adsorption kinetics were measured in fixed-bed experiments at 343, 373, and 423 K with three different propylene molar fractions: 0.29, 0.55, and 0.80. The total pressure was also varied from 110 to 320 kPa. A temperature increase in the curves with high propylene molar fractions can be detrimental to the separation of propane−propylene mixtures by vacuum−pressure-swing adsorption.

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.
