Iridium promoted Ni‐Co/Al<sub>2</sub>O<sub>3</sub>‐ZrO<sub>2</sub> catalyst for dry reforming of methane
Bibliographic record
Abstract
Abstract CO 2 reforming of methane to produce synthesis gas was examined in a fixed bed reactor, using a combined nickel‐cobalt based catalyst supported on a mixed oxide (modified alumina with ZrO 2 ) obtained by the sol‐gel method. The loading of nickel and cobalt was kept at 0.0500 g/g (1:1), while the amount of Ir varied between 0.0000 to 0.0100 g/g. The reforming reactions were performed at 700 °C. The time on stream profile for 360 min showed that all catalysts were very active and stable. The promoter doping of 0.0250 g/gCo‐0.0250 g/gNi‐X g/g Ir/(Al 2 O 3 ‐ZrO 2 ) catalysts augmented the activity regarding the CH 4 and CO 2 by 20 %. The catalysts were characterized by means of TGA, TPR, TPD, XRD, and SEM. The TGA and TPR results showed that the promoter depressed the carbon deposition and upgraded the reducibility of the active metals in that order. While the TPD analysis illustrated the basic sites of the catalyst are of medium strength.

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.
