Thermally coupled catalytic hydrogen combustion-reverse water gas shift reactor: Model-based feasibility study and parametric analysis
Bibliographic record
Abstract
Thermally coupled catalytic hydrogen combustion-reverse water gas shift reactor for CO2 conversion to synthesis gas was designed and numerically analyzed using a 2D model with a shell-and-tube configuration. A transient, pseudo-homogeneous mathematical model was formulated accounting for axial and radial heat dispersion and using experimentally obtained reaction kinetic parameters. Transient reactor behavior was studied to analyze the dynamic behaviour. Steady-state reactor performance was analyzed in terms of temperature and reactant/product distribution, as well as output parameters of practical importance, namely maximum and outlet reactor temperatures, and outlet conversions. Numerical simulations demonstrate the feasibility of the suggested reactor concept and providing insights into thermal management, including the formation of hot spots, appearance of temperature fronts, and the importance of thermal insulation. The model predicted the possibility of 100 % catalytic H2 combustion conversion and 80 % CO2 conversion, with the reactor temperature of ca. 900 °C.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
