Abstract
Abstract Low‐cost Fe 2 O 3 modified activated carbon catalysts have been prepared by a facile incipient‐wetness impregnation method and used for the low‐temperature simultaneous catalytic reduction of SO 2 and NO by CO. The effect of CO, NO, and SO 2 was studied experimentally by transient response method. Removal efficiencies of 95 % for NO and 100 % for SO 2 were obtained, respectively, for the optimum catalyst, in which the amount of Fe 2 O 3 was 10 wt%. It was found that the catalyst was robust enough under SO 2 and NO circumstances; moreover, the prevulcanization of Fe atoms was found to be essential for high efficiency. The reaction mechanism of the simultaneous desulphurization and denitrification reactions of Fe 2 O 3 /AC was proposed to follow both redox and COS mechanisms. These results make activated carbon supported Fe 2 O 3 highly promising for the simultaneous abatement of SO 2 and NO emissions generated during the combustion processes.

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 it
