摘要：
In this study, we aimed to evaluate the physico-chemical, energetic characteristics and fiber dimensions of Anadenanthera colubrina var. cebil, Mimosa tenuiflora and Mimosa arenosa woods, species of Brazilian Semiarid region used for energy. Five trees of each species were logged. The physical characterization of wood was performed in the Forest Products Technology Laboratory (FPTL) of the Federal University of Campina Grande and fiber dimensions and chemical characterization in the Pulp and Paper Laboratory at the Federal University of Vicosa. In general, the woods tested presented similar physical characteristics and fiber dimensions. As for the chemical characteristics, Mimosa tenuiflora showed greater alcohol: toluene solubility and total lignin content, lower holocellulose and ash contents than the other species, presenting three times less ashes than Anadenanthera colubrina var. cebil and half the amount presented by Mimosa arenosa.
