Abstract

The objective of this study was to characterize the tree bark of Araucaria angustifolia, for estimate the energy potential of this biomass as a source of renewable energy and products from biorefineries. Studies have been carried out using thermal analysis (TGA-DTA), X-ray diffraction (XRD), scanning electron microscopy (SEM) and dispersive energy spectroscopy (EDS) for thermochemical and morphological analysis. Through thermal analysis, it is possible to observe in A. angustifolia the thermal effects in the presence of air and nitrogen for a dry sample and its phases in view of the effects of temperature and mass loss. A calorific value measured around 12.23MJ/Kg was also seen, being able to consider this product as an alternative energy source and products such as maltol were identified indicating that substances from biorefineries are present in this biomass.

南洋杉树皮 (BERTOL.) O. Kuntze 的生物精炼产品和能源潜力

摘要

本研究的目的是描述南洋杉树皮的特征，以估计这种生物质作为可再生能源和生物精炼厂产品来源的能源潜力。已经使用热分析 (TGA-DTA)、X 射线衍射 (XRD)、扫描电子显微镜 (SEM) 和色散能谱 (EDS) 进行了热化学和形态分析的研究。通过热分析，可以在A. angustifolia中观察到考虑到温度和质量损失的影响，干燥样品及其相在空气和氮气存在下的热效应。还观察到测得的热值约为 12.23MJ/Kg，能够将该产品视为替代能源，并且鉴定出麦芽酚等产品表明该生物质中存在来自生物精炼厂的物质。
