The species Acrocomia aculeata (Jacq.) Lodd. ex Mart. commonly named as maca�?ºba, is an oleaginous fruit which has 4 kg oil yield per hectare, which is 10 times greater than soy. It is distributed throughout Brazil, but its highest concentration is in the Southeast, North and Midwest of the country. Their exploitation, as subsistence crop has become an alternative for the production of biodiesel, bio-kerosene which can be used for aviation of forest products. The culture of maca�?ºba is in domestication phase, and is still practiced as extractive in a small-scale culture. In this condition, many fruits of maca�?ºba are lost by deterioration of endogenous enzymatic and/or microbial activity, damaging the quality of the oil. Thus, gasification is presented as an alternative use of these residues to generate electricity primarily for its internal use in agro-extractive communities. This study is divided into four parts: Pyrolysis, characterization of the fruit, chromatography of gases and generation of electricity. The steps of pyrolysis and characterization of the fruit have been completed, and it was possible to obtain high values of yield of pyrolysis and potentially higher calorific value, 30.54% and 23.1244 MJ/kg, respectively. The values obtained for the fixed carbon content, volatile content and ash content were respectively 74.615%, 23.18% and 5.44%.
Laura Vieira Maia de Sousa is an undergraduate student in Energy Engineering, at the University of Brasilia, Brazil. She is a fellow of Institutional Extension Program Scholarships since 2014 in “Macaria project - Macaúba and Engineering: Oil production of pulp and almond of Macaúba and gasification of its waste”. She has published an article in the Annals of the VI Meeting of Science and Technology on the topic, “Gasification of Macaúba: The Technical and Chemical Aspects Assessment”.
