Biodiesel from Waste Cooking Oil: Elaboration and Combustion Modeling

Résumé

Modern society is facing two major problems: energy sources depletion and environment degradation because of wastes accumulation. The waste to energy vector contributes to simultaneous solutions of both problems. In this chapter biodiesel production via alkali catalyzed process was produced from waste cooking oils having different acid values. It was concluded that the yield of reaction and final product purity were sensitive to free fatty acid content of raw material, this remark is also true for optimal conditions. Yield of reaction decreased from 105 to 83% reported to oil mass by using waste cooking oil having 0.8 and 6.5 mgKOH/goil acid values respectively. Biodiesel produced from waste cooking oils having acid values lower than 6 mgKOH/goil respects European Norm limits. Produced biodiesel resulted in a 5% energy output increase while used on a diesel engine and a 20% increase in its energy consumption at 1500 rpm. Produced biodiesel was tested over the whole functioning engine range and correlations between operating conditions and heat release parameters were elaborated. The prediction model was compared to biodiesel produced from animal fat residues and the results were very satisfactory.
