Which quality tests (such as viscosity, cetane number, and cloud point) are vital to ensuring Jatropha biodiesel meets fuel standards?

Key tests for Jatropha biodiesel include: viscosity, cetane number, acid value, cloud point, pour point, oxidation stability, and ester content. These ensure compliance with ASTM D6751 or EN 14214 standards. Jatropha biodiesel generally performs well in these tests, though cold flow properties (cloud/pour point) may need improvement via additives or blending. The GlobeCore USB plant produces biodiesel that consistently meets quality parameters through controlled transesterification, moisture removal, and precise chemical dosing—ensuring clean, engine-safe fuel.
