Abstract

fetched live from OpenAlex

There has been increasing interest in alternative fuels made from biomass, which is abundant and renewable. Bio-oil produced by fast pyrolysis of biomass is highly viscous and acidic and has a high water content. To overcome these problems as a fuel, a method of emulsifying bio-oil with biodiesel has been investigated. In the present study, various effects on the mixture stability have been examined. The optimal conditions for obtaining a stable mixture between bio-oil and biodiesel are with an octanol surfactant dosage of 4% by volume, initial bio-oil/biodiesel ratio of 4:6 by volume, stirring intensity of 1200 rpm, mixing time of 15 min, and emulsifying temperature at 30 °C. Furthermore, selected fuel properties, such as viscosity, density, water content, acid number, and average molecular weight, are measured for characterizing the bio-oil/biodiesel mixture. Thermogravimetric analysis (TGA) has been used to further evaluate the thermal properties. Data from the TGA and Fourier transform infrared (FTIR) analyses confirm the presence or absence of a certain group of chemical compounds in the mixture. The kinetic parameters for the thermal decomposition of the bio-oil, bio-oil/biodiesel-rich phase, and pyrolytic lignin-rich phase were obtained from the TGA experiments.

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.
