Pervaporation performance of polydimethylsiloxane/polyetherimide composite membrane for gasoline desulphurization(V) Mass transfer process study
Bibliographic record
Abstract
In order to obtain the properties of the solution and the diffusion for the penetration small molecule in the membrane,and also to study the mechanics of membrane separation process for directing the choice of membrane materials,inverse gas chromatography method is confirmed to study the \lation of the solvent and polymer systems.The infinite dilute activity and diffusion coefficients of thiophene,2-methyl thiophene,2,5-dimethyl thiophene,n-butyl mercaptan,n-butyl sulfide and heptane in cross-linked PDMS were obtained in the temperature range of 80~100 ℃ by inverse gas chromatography.The results showed that the order of infinite dilute activity coefficients was: thiophene 2-methylthiophene 2,5-dimethylthiopheneheptane n-butyl sulphide n-butyl mercaptan,and the order of infinite dilute diffusion coefficients was: thiophene 2-methylthiophene 2,5-dimethylthiopheneheptane n-butyl mercaptan n-butyl sulphide.This work makes a foundational contribution to further investigation on gasoline desulfurization and practical industry application.

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.
