Abstract
Simultaneous CO 2 /SO 2 capture characteristics of three limestones were investigated in a pilot scale fluidized-bed reactor. For each of these sorbents, the measured CO 2 capture capacity decreased as the number of cycles increased and as the SO 2 concentration increased. On the other hand, the SO 2 capture increased with the number of cycles and the SO 2 concentration. The total calcium utilization decreased as the number of cycles increased, but the effect of SO 2 concentration on the total calcium utilization depended on the sulfation pattern of limestone. For one limestone (with unreacted-core-type sulfation), the total calcium utilization decreased with increasing SO 2 concentration. However, for the other two limestones (with uniform-type sulfation), the total calcium utilization was almost independent of SO 2 concentration for the range investigated. The results show that SO 2 reduces the CO 2 capture capacity of limestone and indicate that the sulfation patterns affect the CO 2 capture capacity.

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
