Abstract

This research investigates the relationship between hardness and microstructure obtained through SEM-EDS analysis of palm oil waste-based biocoke. The mechanical qualities and chemical composition of biocoke are being studied concerning the influence of temperature conditions. The manufacturing temperature of biocoke may vary between 150 °C and 190 °C. Utilizing SEM-EDS, we were able to characterize the microstructure and analyze the elemental composition, while the Hardness Shore D approach was used for the most complex materials. These results highlight the possibility of optimizing production temperature to produce biocoke with better mechanical performance. They show a positive correlation between biocoke hardness and structured carbon content. At 150 °C and 180 °C, respectively, the EFB biocoke reached its maximum hardness level of 62 ± 5. At 190 °C, OPM biocoke generated a 60 ± 5 times greater hardness than that of OPM and OPF biocoke. The OPT biocoke sample had the highest porosity with a score of 0.86, or 85.76%. Furthermore, compared to EFB biocoke, OPM and OPF biocokes had a priority of 0.84 (84.20%) and 0.83 (83.48%), respectively. Biocoke hardness is a quality indicator of physical and chemical qualities; the vital link between biocoke hardness, structural features, and elemental composition supports this idea.

基于棕榈油废料的生物焦炭的硬度与 SEM-EDS 表征之间的相关性

本研究调查了通过 SEM-EDS 分析获得的以棕榈油废料为基础的生物焦炭的硬度和微观结构之间的关系。目前正在研究生物焦炭的机械质量和化学成分对温度条件的影响。生物椰壳的制造温度可在 150 °C 至 190 °C 之间变化。利用扫描电子显微镜-电子显微镜（SEM-EDS），我们能够确定微观结构的特征并分析元素组成，而硬度邵氏 D 方法则用于最复杂的材料。这些结果凸显了优化生产温度以生产具有更好机械性能的生物焦炭的可能性。结果表明，生物沸石的硬度与结构碳含量之间存在正相关。在 150 °C 和 180 °C 时，EFB 生物炊具的硬度分别达到 62 ± 5 的最高水平。OPT 生物陶粒样品的孔隙率最高，为 0.86 或 85.76%。此外，与 EFB 生物焦炭相比，OPM 和 OPF 生物焦炭的优先级分别为 0.84（84.20%）和 0.83（83.48%）。生物焦炭硬度是物理和化学质量的质量指标；生物焦炭硬度、结构特征和元素组成之间的重要联系支持了这一观点。
