Preparation and characterisation of Cao nanoparticle for biodiesel production from mixture of edible and non-edible oils
Bibliographic record
Abstract
Calcium nitrate (CaO/CaN) and snail shell (CaO/SS) were successfully utilised for the development of CaO nanoparticle and used in biodiesel synthesis from a mixture of edible and non-edible oils. These solid base heterogeneous catalysts were characterised by FT-IR, XRD, and TGA techniques. Debye-Scherer equation also calculated the average crystalline size of a nanometer. The comparable catalytic activity of CaO/CaN and CaO/SS catalyst was also studied for biodiesel production and found the increment of biodiesel yield from 88% to 92% using CaO/SS. The used optimum reaction conditions were: 6 wt% catalyst loading, 65°C reaction temperature, 12:1 methanol: oil molar ratio and four hr of reaction time. This research shows that developed basic nano catalyst from snail shell exhibit good catalytic activity. Five reusability runs were also done and found that no loss of catalytic activity up to five runs.

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.
