Evaluation of Biomass Properties for the Production of Solid Biofuels

ABSTRACT The efficient use of biomass as fuel requires prior knowledge of the composition and properties of the material in order to be able to develop technologies for its efficient combustion while ensuring that emissions of pollutants remain within acceptable limits. Therefore, the analysis of the physical and chemical properties of these materials is essential in order to evaluate their potential for energy purposes. Given the need for improved understanding of biofuels, this study aimed to characterize biomass waste obtained from the manufacturing process of wood panels and urban waste for the production of solid biofuels. Biomass wastes were characterized in terms of their physical and chemical properties. Wastes that presented the poorest qualities for use as fuels were eucalyptus bark, industrial waste, and sweepings, which had high ash contents and low calorific values. The remaining wastes showed satisfactory characteristics for use as solid biofuels.

摘要 生物质（biomass）作为燃料的高效利用，需预先掌握物料的组成与特性，方可研发出高效燃烧技术，同时确保污染物排放控制在可接受范围内。因此，对这类物料的物理与化学特性开展分析，对评估其能源利用潜力至关重要。鉴于亟需加深对生物燃料的认知，本研究旨在对取自人造板生产工序与城市废弃物的生物质废料进行表征分析，以用于制备固体生物燃料（solid biofuels）。本次研究从物理与化学特性维度对上述生物质废料进行了表征分析。其中，桉树树皮、工业废料与清扫碎屑这类废料的燃料品质最差，其灰分含量（ash content）偏高且热值（calorific value）偏低；其余废料则具备用作固体生物燃料的合格特性。
