Predicting cetane number, kinematic viscosity, density and higher heating value of biodiesel from its fatty acid methyl ester composition

► Experimental methodology for quantifying the FAMEs of biodiesel. ► New empirical correlations to estimate the physical properties of FAMEs from the structural features of molecules. ► Good agreement between experimental and calculated physical properties. ► Simple mixing rules based on mass and mole fraction composition to connect the physical properties of individual FAMEs according to the biodiesel.
