Résumé:
In recent years, it has been sought among the oil sources, which adds good conditions of oxidative stability for the production of biodiesel and its blends. And, therefore, contribute to good quality of the biofuel during the period of storage. The oil moringa Lam. With seeds of high oil content emerges as an alternative to obtain biodiesel, due to the fact that it has antioxidant properties, besides allowing the cultivation in non-arable areas. Thus, this work investigates the efficiency during the storage process of Moringa oil biodiesel and its Ecodieseis, through physicochemical, thermal and microbiological properties. The research was performed with an experimental procedure, in a laboratory scale. Moringa oil was obtained by chemical extraction, using the Soxhlet type extractor, and obtained yield around 38.1%. The biodiesel was obtained by molar ratio of the ethyl alcohol / oil in the proportion 6: 1, in the presence of 1,5% of the catalyst in relation to the mass of the oil. The reaction yield in relation to the mass of the moringa oil for biodiesel was 79.30%. Moringa ethyl biodiesel presented a high induction period (10.2 h), being quite resistant to oxidation, as it contains approximately 76% of monounsaturated fatty acid ester in its fatty chain. On the other hand, a gain in oxidative stability was observed, as the concentration of diesel is higher in the mixture (biodiesel / diesel). However, the use of these mixtures is considered a good alternative, due to the oxidation resistance factor of the final product. Finally, this work demonstrated the excellent conversion of the oil into biodiesel and the stability during the storage period of biodiesel and its oil moringa.
