Simultaneous optimization of carbon yield and iodine adsorption of <scp>ACFs</scp> derived from carpet wastes
Bibliographic record
Abstract
Abstract Recycling post‐consumer carpet waste is a critical consideration for decreasing the environmental hazard of non‐biodegradable plastics. Therefore, the manufacturing of activated carbon fibres (ACFs) from post‐consumer carpet waste treated with KOH was modelled and optimized by the response surface methodology (RSM). The simultaneous effects of carbonization rate, pyrolysis temperature, and activation time on the performance of carpet waste‐based ACFs were studied. Box–Behnken design (BBD) was applied to study the influence of three significant processing parameters on the carbon yield and iodine adsorption of synthesized ACFs. The RSM analysis established that pyrolysis temperature was the most important parameter affecting the ACFs' performance. The optimum settings that led to the production of high carbon yield and iodine adsorption of ACFs were a carbonization rate of 5.4°C/min, pyrolysis temperature of 705.7°C, and activation time of 83 min. The carbon yield and iodine adsorption under the above conditions were obtained at 49.8 ± 0.9 wt.% and 1351 ± 45 mg/g, respectively. BBD has been established to be a powerful approach in modelling and optimization to achieve high‐quality of iodine adsorbents from carpet wastes.

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.
