Large-scale biodiesel production from Moroccan used frying oil

Biodiesel was synthesized at large scale (400L by Batch). The ¹H-NMR, ¹³C-NMR, gas chromatography, and FT-IR analyses of the final product confirmed that in the chosen experimental conditions, the reaction is total. The biodiesel does not contain traces of glycerol. The biodiesel quality parameters that are borderline do not pose any particular problem. The electricity generator diesel engine are run with the synthesized biodiesel without any modification.
