Pyrolysis of predried dyeing sludge: Weight loss characteristics, surface morphology, functional groups and kinetic analysis
Bibliographic record
Abstract
Abstract The weight loss characteristics, surface morphology, functional group, and kinetic parameters of predried dyeing sludge (PDS) pyrolysis was studied for the first time in this paper. The contents of both volatile matter and organic matter in PDS char both decreased with the increase of pyrolysis temperature. The PDS pyrolysis process can be divided into four stages: S 1 (30°C‐180°C)—water evaporation, S 2 (180°C‐500°C)—decomposition of organic compounds such as aliphatic compounds and biomass fibres, S 3 (500°C‐900°C)—decomposition of the former stage residues, and S 4 (900°C‐1350°C)—decomposition of carbonaceous material remaining in the char and vaporization of partial ash. With the increase of pyrolysis temperature, the number density of small spherical particles on the PDS particle surface increased. The decomposition of aliphatic hydrocarbon was basically completed at 700°C. The average activation energy of PDS in S 2 ‐S 4 stages were 172.93, 445.65, and 301.76 kJ/mol, respectively. The pyrolysis reaction of PDS samples could be described by n th‐order reaction mechanism function.

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.
