Extração do óleo, produção e caracterização de propriedades físicas do biodiesel de sementes de maracujá - Passiflora edulis

Abstract

The oil extracted from the seeds of passion fruit (Passifloraedulis) can be used for a lot of industrial purposes, being applied in cosmetics, paints, soaps and others. Through the encouragement of biofuels production and the study of different sources of raw materials in recent years, the biodiesel produced from the oil extracted from the seeds of passion fruit, presents itself as viable alternative for producing regions. For the present study, the passion fruit seeds were washed in order to remove the leavings of fruit and subsequently dried at shadow. They were mechanically pressed by Ecirtec MP-40 and the final oil, which has a density of 924,29kg.m-3and a kinematic viscosity of 27,918mm².s-1 was subjected to filtration process and phosphoric acid degumming 5%. The production of biodiesel was performed by ethyl route using NaOH as a catalyst. We used a mechanical stirrer and an ultrasound in the process. Thereafter, physical properties were evaluated as the kinematic viscosity of the fuel, which were 4,197 mm2 .s -1.
