Abstract

Abstract In this work, the process parameters of batch hydrothermal liquefaction of kitchen residue were optimized with the yield of bio-oil as reference, including reaction temperature, residence time and initial pressure. According to the experimental results, the bio-oil yield of kitchen residue was the highest (39.73%) under the reaction conditions of 6 MPa, 300 °C and 30 min. The elemental content and components of bio-oil were characterized by organic element analyzer and gas chromatography/mass spectrometer. The surface and structural properties of biochar were detected and analyzed by Fourier transform infrared spectrometer, scanning electron microscope and surface area and porosity analyzer.

亚临界条件下餐厨残渣生物油水热液化工艺的优化

摘要以生物油收率为参考，对餐厨残渣分批水热液化的工艺参数进行了优化，包括反应温度、停留时间和初始压力。实验结果表明，在6MPa、300°C和30min的反应条件下，餐厨残渣的生物油收率最高（39.73%）。通过有机元素分析仪和气相色谱/质谱仪对生物油的元素含量和组分进行了表征。利用傅立叶变换红外光谱仪、扫描电子显微镜、比表面积和孔隙率分析仪对生物炭的表面和结构特性进行了检测和分析。
