Generación de hidrógeno a partir de la gasificación solar de combustibles sólidos utilizando un reactor de medios porosos híbrido
Bibliographic record
Abstract
Hidrógeno (H2) y gas de síntesis pueden ser producidos a partir de diversas fuentes mediante reformado de vapor y oxidación parcial. La combustión híbrida filtrada (HFC) consiste en la gasificación de combustibles sólidos o, simultáneamente, en el reformado de combustibles gaseosos y sólidos, sosteniendo reacciones homogéneas y heterogéneas, alcanzando altas temperaturas en el frente de reacción. Este trabajo desarrolla un modelo matemático para generar H2 utilizando un reactor HFC, mediante gasificación del combustible sólido con aporte solar, utilizando COMSOL Multiphysics. Se consideró un lecho poroso de esferas de alúmina y partículas de carbón sub-bituminoso dispuestas aleatoriamente y concentrando la energía solar mediante una placa emisora. El rendimiento de hidrógeno fue 86.5%, eficiencia solar-combustible 49.5% y eficiencia energética 72.3% para 600 kW/m2 de potencia solar. En base a los resultados, esta investigación proyecta la producción de H2 a partir de combustibles fósiles, representando una línea base para la gasificación solar.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
