Study of potassium salts on sawdust pyrolysis: Kinetics and thermodynamic parameters using isoconversional and Criado's master plot methods
Bibliographic record
Abstract
Abstract In this study, the effect of potassium salts on sawdust pyrolysis with respect to kinetics and thermodynamic parameters was investigated. Kinetic triplet (activation energy, pre‐exponential factor, and reaction mechanism) and thermodynamic properties (enthalpy change, entropy change, and Gibbs free energy) were determined using isoconversional and Criado's master plot methods, respectively. Thermogravimetric analysis (TGA) was carried out in N 2 environment at 5, 25, and 50°C/min from 30 to 800°C. A series of analytical techniques were utilized to fully characterize the raw materials. Analysis of TGA data was performed using isoconversional model. The results suggested that the addition of potassium carbonate showed catalytic effect on the thermal degradation of sawdust by affecting the kinetic triplets and thermodynamic properties. However, the presence of potassium chloride in sawdust pyrolysis is a complex and either promoting or deterring effect was primarily dependent on the degree of conversion.

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.
