Study of Propane Oxiditive Dehydrogenation to Propene with Carbon Dioxide on Pd-Cu/MoO_3-SiO_2 Catalyst
Bibliographic record
Abstract
MoO3SiO2 (MoSiO) surface complex supports were prepared by surface modification PdCu bimetallic catalysts were prepared by incipient impregnation BET, TPR and IR techniques have been used to investigate the structure of catalysts and chemisorption states of CO2 and C3H8 Horizontal type chemisorption of CO2 is found; C3H8 is chemisorbed on terminal O of Mo=O bond through H of methylene and one of methyl The catalysts were tested in the reaction of oxidative dehydrogenation of propane with carbon dioxide to propene in a microreactor In the condition of ambient pressure and 600℃, the conversion of propane was 2694%, and the selectivity of propene was 7834% By relating the physical and chemical characters of catalysts with their performance in reaction, a reaction mechanism was proposed and the factors which influence the activity of the catalysts were also studied

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.
