In the production of biodiesel from Jatropha curcas, are produced residues in the peel and of pie form. One alternative use of these residues is in the energy production. The present work analyzed the energy potential of the peel and the pie of Jatropha curcas in the following conditions: in natura and charcoal, determining: the moisture content (VITAL, 1997); the ash, fixed carbon and volatile matter (ABNT NBR 8112/86); the density and the gravimetric yield. The peel presented: moisture of 18,9%; density of 100kg/m3; volatile matter of 72,6%, fixed carbon of 13% and 14,4% of ashes and heat combustion of 3.641kcal/kg. The carbonized peel produced 38.1% of charcoal, with: 29% of volatile matter, 45% of fixed carbon and 25% of ashes; and heat combustion of 3.954kcal/kg. The pie presented: moisture of 2.41%, 601kg/m3 of density; volatile matter of 77.84%, fixed carbon 14.21% and 7,95% ashes and 5.122kcal/kg of heat combustion. In the carbonization of the pie, 32% of charcoal was produced containing: 18.27% of volatile matter, 71.29% of fixed carbon, 10.43% of ashes and heat combustion of 6.234kcal/kg. The high ashe contents are related to the fertilization of the plant. |
