Abstract

fetched live from OpenAlex

Sawdust was pyrolyzed in a fixed-bed tubular reactor. The roles of the pyrolysis temperature, sweep gas flow rate, condensation temperature, and heating rate in the yields of the products were investigated. The obtained char, gas, and bio-oil yields ranged between 20 and 27, 36 and 45, and 33 and 45 wt %, respectively, at different pyrolysis conditions. According to the results obtained under the conditions of this study, the effects of the pyrolysis temperature, sweep gas flow rate, and heating rate on the yields are more significant than the effect of the condensation temperature. The chemical characteristics of the pyrolysis bio-oil and char obtained under optimal operational conditions were identified by elemental and calorific analyses. The bio-oil was analyzed using chromatographic and spectroscopic techniques.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
