Abstract

fetched live from OpenAlex

Biodiesel as an alternative and renewable fuel could be applied in diesel engines in order to reduce air contamination and dependence to fossil fuels. So far, various processes were prepared for biodiesel production, but using transesterification method via base catalyst in batch reactors could result in a reasonable yield of biodiesel. At the present study, a batch tank reactor equipped to a helical ribbon-like agitator was designed and manufactured. Using this reactor, the production efficiency was considerably promoted and the required residence time was reduced. Experiments were conducted at 6:1 molar ratio of alcohol to refined soybean oil, operational temperature of 64?C, KOH concentration of 1%wt oil, and three levels of agitation speed; 600, 750, and 900 rpm. The agitator design and its helicon movement led to a uniform phase formation of insoluble alcohol and oil. Therefore, at 900 rpm stirring speed and after 20 min residence time, 97.3% conversion of triglycerides to methyl esters (biodiesel) could be achieved.

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.
