Energy potential of Eucalyptus spp. Clone biomass. in the northern region of the legal amazon

Abstract

The objective of this research was to characterize the energetic properties of the biomass of the bole and twig of clones of Eucalyptus spp. for direct burning and charcoal production. To characterize the wood of the bole and the branch, three trees were selected using the simple random method, from which discs with a thickness of 5 cm (base, middle and top), were obtained from these same trees and samples of the branch were obtained. The biomass of the bole and twig of Eucalyptus urophylla x Eucalyptus gradis presented acceptable characteristics for both direct burning and charcoal production. However, charcoal from bole biomass presented energy properties of total yield in charcoal (33.23%), fixed carbon content (63.50%), higher calorific value (7047.19 kcal/kg) and ash (0.23%) within the recommended range for quality charcoal. A carbonization rate of 500°C is recommended, as it presented a higher percentage of fixed carbon and consequently a higher calorific value and fixed carbon stock.
