CARACTERIZAÇÃO ENERGÉTICA DO CARVÃO VEGETAL DE Eucalyptus urophylla x Eucalyptus grandis PLANTADOS NO OESTE DO PARÁ

There is no information on the energetic characteristics of eucalyptus coal planted in the Amazon region. There are no studies that define suitable parameters for these new materials aiming at the main indicators of energy quality. The objective of this work was to perform the energy characterization of Eucalyptus urophylla x Eucalyptus grandis charcoal coming from planting in the region of Monte Alegre, western Para State. Wood samples from Eucalyptus urograndis trees at nine years of age, carbonized at 500oC and at 1.7°C.min -1 . It was evaluated the gravimetric yield in coal, apparent density, higher calorific value and fixed carbon contents, volatile materials and ashes. The existence of potential of the species was verified based on the characteristics evaluated. KEYWORDS: Eucalyptus urograndis , Plantations, Quality parameters.
