Abstract
Abstract The isobutane/butene alkylation process catalyzed by an acid solution is widely used to obtain high octane number gasoline components. However, limited by the mass transfer and mixing of the acid solution and the hydrocarbon liquid–liquid system, the product performance needs to be improved. Here, the alkylation reaction was strengthened by combining the chemical regulation of the reactant system and process intensification. Three homologs of sulphates and two hydrophilic surfactants were used as additives to regulate the properties of the acid solution, and the effect of different additives on isobutane/butene alkylation was investigated in a rotating packed bed. The Hammett acidity and solubility of isobutane in acid solutions with different additives were measured, and their synergistic effects on alkylation performance were explored. Under relatively mild conditions (the reaction at 8°C and an isobutane/butene ratio of 30:1), an excellent alkylate with a research octane number of approximately 99 was obtained, showing good industrial application prospects.

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
