Abstract

fetched live from OpenAlex

Simultaneous carbonation and sulphation have been investigated to simulate non-calcining conditions at FBC temperatures (750–850°C) using an atmospheric-pressure thermogravimetric reactor (TGR) with up to 80% CO2 in the gas stream to extend the pressure range of applicability of the results. This investigation was undertaken to provide insight on simultaneous carbonation and sulphation and to provide knowledge relevant to FBC, including PFBC, operations. Two calcium-based sorbents (one limestone and one dolomite) were tested with particles of diameter 212–250 μm and 500–600 to determine the effects of operating conditions such as temperature, CO2 and SO2 concentrations, particle size and reaction time on the sorbent performance. SO2 was found to impede CO2 capture; on the other hand, CO2 enhanced the capture of SO2. The calcination rate was also observed to decrease as a result of the presence of the sulphate layer.

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.
