Abstract

In this study, slow pyrolysis of the camelthorn plant process was conducted to produce bio-oil, biochar, and gas. The pyrolysis process was conducted between 400 and 550 °C under pressure 10 bar using a fixed bed reactor. The pyrolysis products were bio-oil, biogas, and biochar. These products were characterized using Fourier-transform infrared (FT-IR) model, gas analyzer, chromatographic analysis using GC–MS, and thermogravimetric analysis (TGA). The GC–MS results demonstrated composition of bio-oil, detecting several organic substances including levoglucosan, furan, acetic acid, phenol, and long-chain hydrocarbon. To further understand the chemical composition of bio-oil, FT-IR spectroscopy was conducted to determine functional groups. The thermal behavior and degradation of the camelthorn sample were studied using TGA which provided thermal stability and prospective applications. Gas composition was measured using a gas analyzer. These analytical methods’ results offer insight on the camelthorn plant’s potential as a sustainable bio-oil and biochar sources, and these findings contribute to the advancement of biomass conversion expertise and provide vital insights for sustainable energy production.

利用缓慢热解技术从骆驼刺植物中生产生物油并确定其特性

本研究对骆驼刺植物进行了缓慢热解，以生产生物油、生物炭和气体。热解过程在固定床反应器中进行，温度为 400 至 550 °C，压力为 10 巴。热解产物为生物油、沼气和生物炭。使用傅立叶变换红外（FT-IR）模型、气体分析仪、气相色谱-质谱（GC-MS）色谱分析和热重分析（TGA）对这些产物进行了表征。气相色谱-质谱分析结果表明了生物油的成分，检测到多种有机物质，包括左旋葡聚糖、呋喃、乙酸、苯酚和长链烃。为了进一步了解生物油的化学成分，还进行了傅立叶变换红外光谱分析以确定官能团。使用 TGA 研究了骆驼刺样品的热行为和降解情况，该方法提供了热稳定性和应用前景。使用气体分析仪测量了气体成分。这些分析方法的结果有助于深入了解骆驼刺植物作为可持续生物油和生物炭来源的潜力，这些发现有助于生物质转化专业知识的发展，并为可持续能源生产提供了重要见解。
