Comparative study of two activated carbons from Borassus aethiopum produced in electric and artisanal furnaces
Bibliographic record
Abstract
The comparison of activated carbons of Borassus aethiopum produced in an electric and artisanal furnaces showed similarities and differences in their characteristics.The activated carbon produced in an electric furnace (BA-AC FE) with a specific surface area of 888 m 2 /g is less microporous than the activated carbon produced in an artisanal furnace (BA-AC FA) which has a specific surface area of 1431 m 2 /g.Also, with its BM index (IBM) of 329.5 mg/g the BA-AC FE is more macroporous than the AC-BA-Fa which has an IBM of 28.8 mg/g.This, importance of macroporosity on the AC-BA-FE allowed to obtain an abatement rate of 95.11 % of BM against 72.24 % for the AC-BA Fa.Both carbons have type IV adsorption isotherms.In view of the good characteristics of the BA-AC FA activated carbon, the water issue can be improved in rural areas by building artisanal furnaces.These will allow to produce quality activated carbon and to design carbon filters.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
