Abstract

This study delves into the intriguing prospect of concurrently utilizing macadamia husk and nutshell for biomass gasification, aiming to generate sustainable energy. By scrutinizing their physicochemical properties such as thermal behaviors, char conversion kinetics, and syngas properties we unveiled an intriguing revelation. The fusion of these residues creates an apt feedstock for biomass batch-gasification in industrial settings. This resultant blend inherits distinctive traits from its constituent parts, profoundly influencing gasification reactivity and fostering heightened char conversion efficiency and stability. Spanning 2165 s, this process exhibited commendable control. Furthermore, the residue amalgamation consistently yields an average syngas flow rate of 0.00136 [mol (g minute)−1], predominantly composed of CO at 0.00097 [mol (g minute)−1], constituting over 71 % of the syngas. These findings underscore the potential of merging these residues to optimize the conversion process and bolster resource availability, thus propelling advancements in waste-free energy production and sustainable energy technologies.

将澳洲坚果加工产生的异质固体残渣作为高温气化的可行原料
本研究深入探讨了同时利用澳洲坚果壳和果壳进行生物质气化以产生可持续能源的有趣前景。通过仔细研究它们的理化特性,如热行为、炭转化动力学和合成气特性,我们发现了一个令人感兴趣的启示。这些残留物的融合为工业环境中的生物质批量气化提供了合适的原料。由此产生的混合物继承了其各组成部分的独特特性,对气化反应性产生了深远影响,并提高了炭转化效率和稳定性。在 2165 秒的时间内,该工艺表现出了值得称道的控制能力。此外,残渣汞齐化可持续产生 0.00136 [摩尔(克/分)-1] 的平均合成气流量,其中主要成分为 0.00097 [摩尔(克/分)-1]的 CO,占合成气的 71%以上。这些发现强调了合并这些残留物以优化转化过程和提高资源可用性的潜力,从而推动无废物能源生产和可持续能源技术的进步。
