PRODUCT DISTRIBUTION AND REACTION KINETICS IN THE AROMATIZATION OF YANHUA FCC GASOLINE
Bibliographic record
Abstract
y using Yanhua FCC gasoline and a selected fraction of Yanhua FCC gasoline as feedstocks, the effects of reaction temperature, Weight Hour Space Velocity (WHSV), and feedstock performance on yields of LPG, aromatics, and propylene production were investigated in a confined fluidized bed reactor. The experimental result show that yields of aromatics, propylene, and aromatics + propylene for both Yanhua FCC gasoline and fraction of Yanhua FCC gasoline increase with the increase of reaction temperature at the same WHSV. Yields of aromatics, propylene, and aromatics + propylene decrease with the increase of WHSV at the same reaction temperature. Eight-lump kinetics and ten-lump kinetics are pointed out. The experimental results show that both kinetic models can predict the distribution of gasoline conversion and the composition of hydrocarbons of gasoline products under the different reaction conditions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
