Storage Stability of 50% Biodiesel Blends and Neat Biodiesel Produced in North America

Summary

This report investigates the long-term storage stability of biodiesel and its blends produced in North America, addressing concerns about fuel degradation due to oxidation. Researchers conducted an accelerated aging study over 12 weeks at 43°C, simulating 12 months of storage for 26 different fuel samples. The findings indicate that B100, B20, and B50 blends with an initial induction period greater than 6 hours exhibit robust storage stability, with no significant acid number or insoluble formation observed over the simulated year.
