Preparation and Evaluation of Resistance Coke Formation Catalysts in Combined Reforming of Methane Using Steam and Oxygen for the Production of Synthesis Gas
Bibliographic record
Abstract
Ni-based catalysts with different promoters, such as Fe, La, Zr, Ce, and Ca, were prepared using the one-step sol–gel method and tested for their performance in the combined reforming of methane using steam and oxygen. The catalysts were characterized by XRD, SEM, TPO, BET, and TPR analysis. The consequences revealed that deposited carbon was lower on the surface of the 10% Ni-3% Fe-MgO·Al 2 O 3 catalyst in oxygen-combined CH 4 reforming. The Fe 2 O 3 -doped sample depicted the highest CH 4 conversion, more than 65%, and showed a higher catalytic stability for O 2 reforming of methane. In addition, introducing steam into the feeds benefited the performance of catalysts due to lower coke formation, and the H 2 /CO ratio was changed from 1.5 to 3 at 700 °C. It is concluded that the high catalytic efficiency of the Fe 2 O 3 -doped sample in combined reforming of methane was associated with its high reducibility and more reduction of NiO species.

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.
