Electronic Arch VL - 6 IS - 1 SE - Ciências Agrárias DO - 10.36560/61201491 UR - https://sea.ufr.edu.br/SEA/article/view/91 SP - 7 - 17 AB - <p><em>This work aimed to evaluate the production of charcoal from the hedgehog of the Brazil nut using metal drums as a reactor, considering the adaptive feature for mobility, typical of this exploitation. The average time of carbonization was relatively short, 4:45 hours, which generated a yield of charcoal of 19.11%. The content of material with incomplete carbonization was of 35.77%. His basic density was 0.631g.cm<sup>-3</sup>, since the bulk density was 0.231 g.cm-3. The average moisture content of the charcoal produced was 4.71%. Volatile materials, amounted to 20.79% of the total mass. The ash content was 0.87% and the fixed carbon was 78.33%. The calorific value was 7252.98 kCal.kg<sup>-1</sup>. Thus, it can be conclude that the method</em><em> </em><em>of the drum is adapted to charcoal producing from the hedgehog of the Brazil nut, however, improvements in thermal insulation of the reactor can be proposed for future work; gravimetric yield in charcoal was low when its performance is compared to other methods of carbonization, probably by the lack of thermal insulation; carbonization time in the reactor was considerably lower than those obtained for the carbonization in muffle for similar products. </em></p> ER -
