Adsorption Kinetics of Nickel Etioporphyrin on VTB-Asphaltene in N-Pentane Solution
Bibliographic record
Abstract
It is important to find out how to strengthen the interaction between nickel porphyrins and asphaltene in the alkane solvents of the low molecular weight for raising the removal rate of nickel in the solvent deasphalting process. Therefore, the adsorption kinetics, which describes how the nickel etioporphyrins are adsorbed on asphaltene (the vacuum residue of Canadian oil sands bitumen (VTB)) in the n-pentane solvent, are investigated. The results show that a certain amount of nickel porphyrins is absorbed on the asphaltene of VTB, which means there is a certain adsorption between asphaltene and nickel porphyrins. The adsorption rate is affected by the dosage of asphaltene, the concentration of the n-pentane solution containing nickel porphyrins and the temperature. A comparison in the four kinds of kinetic models on the overall adsorption rate shows that adsorption process can be perfectly described by the pseudo second-order equation.

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.
