Effects of Rapid-heating and/or High-pressure Conditions on Coke Making, Examined Using a Synthetic Model Compound
Bibliographic record
Abstract
This study investigated the mechanisms by which rapid-heating and/or high-pressure conditions can improve the thermal fluidity of coal, using a synthetic compound as a model for low-molecular weight (Mw) compounds in coal. The compound had one quinoline ring and two naphthalene rings, C36H33N, Mw of 479, and a boiling point (bp) of ~520°C. Rapid heating (> 10°C/min) overcame the evaporation rate of the compound, whereas high pressure (> 1 MPa) increased the bp and suppressed the pyrolysis reaction. These conditions allowed the compound to remain until temperatures > 400°C, although it completely evaporated at 370°C under general heating conditions in a coke oven (3°C/min and 0.1 MPa). The effects of increasing the heating rate from 3 to 10°C/min at 0.1 MPa corresponded to the effects of increasing the pressure from 0.1 to 1.0 MPa at 3°C/min. The compound remaining at temperatures > 370°C can act as a mobile phase and hydrogen donor, thereby increasing the fluidity of coal. It can also serve as a reactant in the coking reaction and increase the coke yield.

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.
