Abstract

The use of biomass obtained by pyrolysis has received great attention due to its favorable characteristics to the improvement of soil quality for agricultural purposes, soil remediation against several types of contaminants and great potential for carbon sequestration. This study aimed to evaluate the physical–chemical characteristics of biochar produced from the endocarp of Syagrus coronata. It was determined the best operational conditions to obtain a biochar with good features to be used in soil as fertilizer. The thermal gravimetric analysis (TGA/DTGA), elemental analysis (EDX), scanning electron microscopy and infrared spectroscopy (FT-IR) techniques allowed the finding that the pyrolyzed at 400 °C was the one that presented a greater stability and more suitable characteristics, in comparison to the other materials. The material in that condition is more favorable to be used as a natural fertilizer to improve the ground standard and, consequently, to stimulate the agricultural productivity.

温度对Syagrus coronata真空热解生产生物炭的影响

摘要

通过热解获得的生物质的使用具有良好的特性，因为它具有改善农业用土壤质量，对几种类型的污染物进行土壤修复以及碳固存的巨大潜力，因此受到了广泛的关注。这项研究旨在评估从矢车菊的内果皮产生的生物炭的理化特性。确定了获得具有良好特性的生物炭用于土壤肥料的最佳操作条件。热重分析（TGA / DTGA），元素分析（EDX），扫描电子显微镜和红外光谱（FT-IR）技术使我们发现在400°C的温度下热解是表现出更高的稳定性和更适合的特性的热解，与其他材料相比。在这种条件下，该材料更适合用作天然肥料，以提高地面标准，从而刺激农业生产率。
