Utilização de óleo e éster-etílico de bocaiúva (Acrocomia aculeata) em um grupo gerador a diesel

Abstract

Faced with current concerns about the greenhouse effect and the pollutants generated by the use of fossil fuels, several studies are currently being conducted to find alternative solutions for power generation and for the transportation sector. An alternative found is the use of the ethyl ester of vegetable origin in partial replacement of the mineral diesel oil. Biodiesel is already being produced and mixed with commercial diesel, but the search for new sources of biodiesel, increasingly advantageous continues. This work investigates the use of bocaiúva oil, a typical Brazilian fruit, as an energy input and raw material for the production of ethyl ester. Tests of oil content in fruits, specific mass and high heat value were carried out. Performance and pollutant emission tests were also carried out on a diesel motor generator: data on actual power, specific consumption, rotation and emission of CO, CO2, NOX and CH4 were collected. The behavior of the bocaiúva oil was better than that of the ethyl ester. For the most part, the emissions did not behave as expected. Therefore, it is suggested that the experiment be redone to prove the results obtained.
