Production of methane from carbon monoxide and carbon dioxide in a plasma-catalytic combined reactor system
Bibliographic record
Abstract
Plasma-catalytic hydrogenation of CO and CO 2 for producing methane was investigated with a catalyst-packed dielectric barrier discharge reactor. The characteristics of methane production from CO/H 2 or CO 2 /H 2 gas mixture were examined with bare alumina, TiO 2 /alumina, Ni/alumina, and Ni-TiO 2 /alumina under plasma and non-plasma conditions. The results obtained with bare alumina and TiO 2 /alumina suggest that either plasmainduced gas-phase reactions or photocatalytic reactions hardly contribute to the conversion of CO and CO 2 . The nonthermal plasma was found to have a promotive effect on the conversion of CO and CO 2 only when nickel-loaded catalysts such as Ni/alumina and Ni-TiO 2 /alumina were used, implying that the nonthermal plasma serves to promote the dissociation of carbon-oxygen bonds of CO and CO 2 adsorbed on the active sites of the catalysts, known as the slowest step of the reaction.

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.
