Abstract

fetched live from OpenAlex

Co-capture of H 2 S and CO 2 by calcium-based sorbents was investigated in a pressurized thermogravimetric reactor with two limestones and one dolomite. Typical test conditions were 850 °C and 0.76 MPa. Syngas was used to simulate gasifier conditions. There was complex interaction between the solid product layers and diffusing ions. Careful control of co-capture operating conditions could cause the cyclic performance of limestone sorbents to approach that where no H 2 S was present. Cyclic operation could lead to higher extents of sulfidation than for H 2 S alone under comparable conditions. H 2 S is much less of a problem than SO 2 in impeding CO 2 capture, even though both reaction irreversibly with lime and limestone under conditions of practical interest.

Full frame distilled prediction

Teacher imitation

Not 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.
