Abstract
The intensification of the reverse water gas shift (RWGS) reaction by water-permeable packed-bed membrane reactors (PBMRs) is studied to produce syngas using a CuO/ZnO/Al2O3 catalyst at 250 °C and 5 bar. Using experimental data from the literature, a modified kinetic model is developed for the RWGS reaction rate of the catalyst at low temperatures. The effects of gas hourly space velocity, H2 to CO2 ratio, H2O/H2 perm-selectivity, and sweep to reactor pressure and flow rate ratios are studied on the performance of the RWGS PBMRs for co- and counter-current flow configurations. The RWGS PBMRs are proven to be effective in overcoming equilibrium limitations of the RWGS reaction under different operating conditions. An optimization is performed to minimize the volume of the RWGS PBMRs to produce syngas for methanol synthesis. The optimization results show that the membranes are effective to produce the desired syngas under different operating conditions and flow configurations.

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
