Abstract
This paper presents experimental studies of circulating fluidized bed based calcium looping gasification (CFB-CLG) system for producing hydrogen-enriched gas from biomass. The merit of this system is that it captures carbon dioxide (CO2) during the process using the inexpensive and easily available sorbent calcium oxide (CaO). The process also regenerates the sorbent internally and produces a relatively pure stream of CO2. A laboratory scale calcium looping gasification system based on a circulating fluidized bed was developed and tested. Experiments conducted to gasify sawdust in the CFB-CLG system shows that it could produce a gas with 81% hydrogen and CO2 as low as 5%. Exergy analysis of the calcium looping system is done and the efficiency is 78.77%.

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
