Formulation of activated carbons and evaluation of methane storage by compression and adsorption
Bibliographic record
Abstract
Abstract Activated carbons were produced from coconut shells by chemical activation using H3PO4 (CAQ1) and ZnCl2 (CAQ2), and used as adsorbents for natural gas storage. CAQ1 presented a wider pore size distribution than CAQ2. Storage evaluations were made in a semi‐pilot unit (0.5–4.0 MPa and 298–313 K). According to the used reactant, at 313 K and 3.0 MPa, the adsorptive capacities were 0.060 g/g (CAQ2) and 0.092 g/g (CAQ1). The shortest storage time to charge the tank to 4.0 MPa was obtained by CAQ2 (3.1 min), compared to CAQ1 (3.4 min), due to its higher specific heat capacity. © 2011 Canadian Society for Chemical Engineering

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.
