In this work, liquid biofuel (bio-oil) was produced by pyrolizing cassava peel. The experiments were conducted isothermally in a fixed-bed tubular reactor at temperatures ranging from 400 to 600°C with a heating rate of 20°C/min. The chemical compositions of bio-oil were analyzed by a gas chromatography mass spectrometry (GC-MS) technique. For the optimization of liquid product, temperature was plotted to be the most decisive factor. The maximum yield of bio-oil ca. 51.2% was obtained at 525°C and the biofuel has a gross calorific value of 27.43 MJ/kg. The kinetic-based mechanistic model fitted well with experimental yield of pyrolysis products with the mean squared error (MSE) of 13.37 (R(2)=0.96) for solid (char), 16.24 (R(2)=0.95) for liquid (bio-oil), and 0.49 (R(2)=0.99) for gas.
在这项工作中，通过热解木薯皮来生产液体生物燃料（生物油）。实验在固定床管式反应器中进行，在 20°C/min 的升温速率下，温度范围为 400 至 600°C。通过气相色谱质谱联用（GC-MS）技术分析了生物油的化学成分。为了优化液体产物，温度被绘制为最具决定性的因素。在 525°C 时，生物油的最大产率约为 51.2%，生物燃料的总热值为 27.43MJ/kg。基于动力学的机理模型与热解产物的实验产率拟合良好，固体（炭）的均方误差（MSE）为 13.37（R²=0.96），液体（生物油）为 16.24（R²=0.95），气体为 0.49（R²=0.99）。
