Abstract

fetched live from OpenAlex

According to the 9-lumped kinetic model and the total kinetic model as well as the mechanism of the F-T synthesis wax hydrocracking process,a 5-lumped kinetic model was established.On the basis of the concept of isomerization factor,the experimental results combined with isomerization reaction simulation and the introduction of cracking probability function,the original 9-lumped kinetic model cracking assumption was improved.Cracking probability function made the model more close to the actual hydrocracking process.There were seven reactions in the 5-lumped reaction kinetic model.Two kinds of kinetic models were compared by using the experimental results over the catalyst consisting of platinum(0.6%,mass)supported on amorphous silica alumina modified with H-β.The average relative error between the 5-lumped kinetic model calculations and experimental values was 3.95%.When conversion was higher than 90%,average relative error was below 0.8%.From the comparison,product selectivity could be well predicted by the 5-lumped model.

Not 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.
