Microwave Catalytic Conversion of SO 2 and NO x over Cu/zeolite
Bibliographic record
Abstract
Abstract: Microwave catalytic technology is a promising technology for flue gas treatment. Cu/zeolite was used as catalyst for microwave catalytic desulfurization and denitrification and for microwave catalytic reduction of SO 2 and NOx with ammonium bicarbonate (NH 4 HCO 3 ) as a reducing agent. Microwave catalytic desulfurization and denitrification efficiency achieved 76.1 and 81.8% separately. The reaction efficiency of microwave catalytic reduction of SO 2 and NO x could be up to 99.8 and 92.8% respectively. The physico-chemical properties of Cu/zeolite catalysts were characterized by X-ray diffraction analysis (XRD), Brunauer-Emmett-Teller measurements (BET), X-ray photoelectron spectrum analysis (XPS), scanning electron microscopy (SEM).The XPS results indicate that sulfide (SO4 2- ), element sulfur (S 0 ) and NH 4 + species exist on the catalyst surface after the reaction. Microwave catalytic SO 2 and NO x removal follows Langmuir — Hinshelwood(L-H) kinetics.

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.
