Compatibilidade de misturas de biodieseis de maracujá e mamona.

Abstract

In the search for alternative raw materials for biodiesel production of the passion fruit presents interesting features such as: adaptation climatic conditions and good oil content, although high levels of unsaturated fatty acids, which may affect its stability. Castor oil is very resistant to water scarcity and their seed is formed from 43 to 50% oil. The aim this work was to evaluate the compatibility of mixtures of biodiesel from passion fruit and castor oil in different proportions, determinating its physicochemical properties and thermal stability. The biodieseis from passion fruit and castor oil and mixtures showed physicochemical parameters within the standards established by the ANP. As for the thermogravimetric curves it was found that biodiesel from castor oil showed greater stability than the passion fruit. The mixtures of biodieseis in the proportion of 1:1 made it more thermally stable as the biodiesel from passion fruit, due fatty acid composition.
