Abstract
The species Acrocomia aculeata (Jacq.) Lodd. Ex Mart. Macaúba common name, is an oleaginous fruit which has 4.000kg oil yield per hectare, ten times greater than soy. It is distributed throughout Brazil, its highest concentration 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 for aviation and by-products of forest products.
The culture of macaúba is in domestication phase, and is still practiced an extractived in a small-scale culture. In this condition, many fruits of macaúba 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 Potential Higher Calorific, 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%.
