Storage stability and corrosive character of stabilised biodiesel exposed to carbon and galvanised steels

- Galvanised and carbon steels have proven to be compatible with biodiesel.
- Biodiesel properties were not affected for a storage time of 56 days.
- Zinc release in non-stabilised biodiesel did not stimulate biodiesel deterioration.
- TBHQ was rapidly consumed in the first days of the corrosion immersion test.
- TBHQ acted as a corrosion inhibitor and enhanced storage stability of biodiesel.
