Catalytic Conversion of 1,2,4-Trimethylbenzene in a CREC Riser Simulator. A Heterogeneous Model with Adsorption and Reaction Phenomena
Bibliographic record
Abstract
The aim of the present work is the development of a heterogeneous kinetic model for the isomerization and disproportionation of 1,2,4-TMB. With this end, experiments are conducted in a novel CREC riser simulator loaded with an FCC catalyst. FCC catalysts were prepared using HY zeolites having different crystallite sizes, namely,0.4 and 0.9 μm. The observed distributions of products are reviewed considering potential shape-selectivity effects and hindered diffusion of products. The adopted modeling strategy allows for the calculation, with little ambiguity, of adsorption constants; heats of adsorption; and kinetic constants, such as energies of activation and preexponential factors.

How this classification was reachedexpand
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.
