Abstract

fetched live from OpenAlex

Sulfur compounds in VGO of SCO(Synthetic Crude Oil) from Canadian oil sand bitumen were identified with GC-PFPD and GCMS methods.The sulfur compounds in VGO of SCO are mainly C3~7-dibenzothiophene,while those in FCC liquid products are short chain dibenzothiophene and a few alkylated benzothiophene and alkylated thiophene,and the percentages of these three sulfur compounds are 82.04%,13.42% and 0.56%,respectively,and they are difficult to be removed by hydrogenation.The mixtures of VGO which mixed with SCO and Dagang in different proportion were processed in FCC reactor.With the increase of proportion of mixtures,the sulfur content of alkylated benzothiophene and alkylated thiophene in FCC liquid products reduce gradually,and the dominant part is short chain dibenzothiophene,especially 4-MDBT indicating the characters of hydrogenation of SCO.The content of sulfur in liquid products and diesel distillate increases,while it is reduced in gasoline distillate.

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.

Full frame distilled prediction

Teacher imitation

Not 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.
