Abstract

Wood residues can go to waste due to a lack of knowledge of their properties. In order to contribute to the use of materials, the objective was to individually assess the physical and chemical characteristics of Amazonian wood waste. Due to the lack of information about most Amazonian tree species, Eucalyptus grandis was defined as a control treatment. The following tests carried out were: granule size, moisture, wood basic density, residuals bulk density, pH, total extractives, lignin, holocellulose, volatile matter, ash, fixed carbon, high and lower heating values and liquid energy density. The evaluated species presented different characteristics for the physical, chemical, and energetic tests of wood residues. In general, the Amazonian species showed superior characteristics in comparison to Eucalyptus grandis for energy production. Qualea paraenses, Cedrela sp., Dinizia excelsa, Ocotea cinerea and Buchenavia grandis need to be further investigated for energy purpose due to the low pH. Based on the data obtained, it would be recommended to adopt pre-treatments as a way to increase the energy performance of biomass.

调查砍伐亚马逊雨林产生的能源浪费

由于缺乏对其特性的了解，木材残留物可能会被浪费。为了促进材料的使用，目标是单独评估亚马逊木材废料的物理和化学特性。由于缺乏关于大多数亚马逊树种的信息，大桉被定义为对照处理。进行了以下测试:粒度、水分、木材基本密度、残余容重、pH、总萃取物、木质素、全纤维素、挥发物、灰分、固定碳、高低热值和液体能量密度。被评价树种在木材残留物的物理、化学和能量测试中表现出不同的特征。总的来说，亚马逊树种在能量生产方面表现出优于大桉树的特征。由于ph值较低，需要进一步研究Qualea paraenses, Cedrela sp.， Dinizia excelsa, ococtea cinerea和Buchenavia grandis的能源目的。根据所获得的数据，建议采用预处理作为提高生物质能源性能的一种方式。
