Effect of CO<sub>2</sub> on catalytic hydrotreatment of gas‐oil
Bibliographic record
Abstract
The aim of this study is to investigate the effect of CO 2 on catalytic hydrotreatement of gas‐oil to evaluate the potential of catalytic co‐ hydroprocessing of petroleum fractions with liquid biomass. A total of six experiments were conducted under low (330 °C), mild (345 °C) and severe (360 °C) operating conditions employing straight run gas‐oil as the petroleum fraction feedstock. During three of these experiments CO 2 was artificially added to the reaction system to assess its impact on the associated catalytic reactions over a commercial CoMo/Al 2 O 3 catalyst. The dedicated experiments revealed a suspending role of CO 2 on hydro‐ desulfurization (HDS), hydro‐denitrogenation (HDN), and saturation reactions, which is attributed to the subsequent hydrogen partial pressure reduction of the reacting system caused by the competitive water gas‐shift and methane reforming reactions.

How this classification was reachedexpand
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.
