Abstract

fetched live from OpenAlex

This project has been designed by CanmetENERGY-Ottawa (CE-O, Natural Resources Canada) and its industrial partner CRB Innovations Inc. to assess the feasibility of sing lignin-derived diesel fuels in order to reduce the emissions of non-biogenic greenhouse gases and criteria air contaminants from the rail sector. These “drop-in” biofuels are hydrocarbon-based blending stocks fully compatible with conventional diesel fuels. CE-O and CRB Innovations Inc. have been working together on the development of technologies to convert lignin (a major component of wood) into renewable fuels under a multi-year task-shared agreement. CE-O develops and carries out the catalytic hydrotreatment whereas CRB deconstructs and fractionates lignocellulosic biomass and catalytically depolymerizes the lignin-rich fraction producing clean “oligomeric lignin feedstock” used by CE-O. In this project, the focus is to verify whether diesel fuel blends, containing lignin-derived diesel, can meet CGSB 3.18 specifications for locomotive fuel and then perform preliminary exhaust emission tests.

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.
