Material-Biodiesel Compatibility – Survey of Industry Experience
Bibliographic record
Abstract
Abstract The regulation in Canada requires that, starting from 2011, the renewable fuel content in diesel is at least 2%. Similar USA requirements resulted in the production of more than 1.5 billion gallons of biodiesel in 2009. Several other countries also produce large amount of biodiesel. Two surveys were conducted in 2011 to understand the industry knowledge and experience with respect to the use of biodiesel. This paper summarizes the salient features from these surveys. This paper additionally focuses on material-biodiesel interaction at various stages between the production of biodiesel and usage. The main findings from these surveys include, Based on the experience gained so far, no major incident of material incompatibility with biodiesel of concentration up to 5% has been reported.Incidents of corrosion and microbiological influenced corrosion have been experienced in the presence of accumulated water; however the incidences are not higher than those experienced in the presence of petroleum diesel alone.No new issues of high-temperature corrosion have been reported in using up to 20% of biodiesel under automotive operating conditions.Materials (both metals and non-metals) that are incompatible with raw biodiesel (B100) have been established and, to a certain extent, are avoided in handling fuels containing biodiesel.

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.
