Abstract

Abstract The objective of this study was to examine the properties of hybrid biochar produced from date palm (D) and pistachio (P) residues and their co-pyrolysis at mixing ratios of 60:40 (by weight). Biochars were produced at 500 °C through pyrolysis in a tube furnace and subsequently characterized. Results indicated that pistachio biochar (PBC) had a high carbon content (81.02 wt%) and a low oxygen content (17.57 wt%). Conversely, the date palm biochar (DBC) had a high ash content (28.11 wt%) and a low carbon content (40.08 wt%). Blending D and P at the specified ratios improved the biochar samples’ gross and elemental contents. Fourier transform infrared spectroscopy (FTIR), X-ray fluorescence spectroscopy (XRF), thermogravimetric analysis (TGA), and field emission scanning electron microscopy (FESEM) were utilized to determine the morphology and structure of the produced biochar.

枣椰树和开心果残渣混合生物炭的潜力评价

摘要本研究的目的是考察由椰枣（D）和开心果（P）残留物生产的杂交生物炭的性质，以及它们在60:40（按重量计）的混合比下的共热解。生物炭的生产成本为500 °C，在管式炉中热解，随后进行表征。结果表明，开心果生物炭具有较高的碳含量（81.02 wt%）和低氧含量（17.57 wt%）。相反，椰枣生物炭（DBC）的灰分含量较高（28.11 wt%）和低碳含量（40.08 wt%）。将D和P以指定的比例混合可以提高生物炭样品的总含量和元素含量。利用傅里叶变换红外光谱（FTIR）、X射线荧光光谱（XRF）、热重分析（TGA）和场发射扫描电子显微镜（FESEM）测定了所制备的生物炭的形态和结构。

期刊介绍： The Journal of Wood Chemistry and Technology (JWCT) is focused on the rapid publication of research advances in the chemistry of bio-based materials and products, including all aspects of wood-based polymers, chemicals, materials, and technology. JWCT provides an international forum for researchers and manufacturers working in wood-based biopolymers and chemicals, synthesis and characterization, as well as the chemistry of biomass conversion and utilization. JWCT primarily publishes original research papers and communications, and occasionally invited review articles and special issues. Special issues must summarize and analyze state-of-the-art developments within the field of biomass chemistry, or be in tribute to the career of a distinguished researcher. If you wish to suggest a special issue for the Journal, please email the Editor-in-Chief a detailed proposal that includes the topic, a list of potential contributors, and a time-line.
