Aqueous Phase Reforming of Model HTL Wastewater with Pt/C and Ru/C Catalysts
Bibliographic record
Abstract
Aqueous Phase Reforming (APR) was conducted at a temperature of 225 °C, a pressure of 450 psi, and with two catalysts: 5 wt.% platinum and 5 wt.% ruthenium supported on active carbon. Single- and multiple-component surrogate feedstocks were tested, indicating that the ruthenium catalyst was the superior catalyst as it consistently outperformed the platinum catalyst with hydrogen yields of 77-100%, compared to the 44-54% yield range of platinum. The wastewater resulting from the Hydrothermal Liquefaction (HTL) of Municipal Sewage Sludge (MSS) as a feedstock was tested at 225 and 250 °C, and at 450 and 650 psi. Results demonstrated that while hydrogen can be produced from MSS-HTL wastewater using a ruthenium catalyst supported on carbon, catalyst deactivation was severe. Future work is suggested to investigate methods for preventing the deposition of sub-micron particles on the catalyst.

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.
