Experimental and prediction of physics and chemical properties of biodiesel



The proposal of present research includes producing biodiesel fromblends of virgin castor oil (VCO) and waste frying oil (WFO). Physicochemicalcharacterization of VCO (B1), WFO (B2) and three different blends (B3:50%VCO+50%WFO; B4:25%VCO+75%WFO; B5:75%VCO+25%WFO) wereevaluated. The results indicated that the content of waste frying oils of the blendsinfluenced the physical-chemical properties of the biofuel, but did not influence therheological behavior of the biodiesel, which tended to the Newtonian. By anotherhand, physical and chemical properties of biodiesel were predicted by using moleculardescriptors and several architectures of artificial neural networks. The optimumarchitecture (configuration 10-2-20-3) was found for the lowest deviations in the threedependent variables (fuel acidity, ketone index and kinematic viscosity).
