Empty fruit bunches (EFBs), a waste material from the palm oil industry, were subjected to pyrolysis and gasification. A high content of volatiles (>82%) increased the reactivity of EFBs, and more than 90% decomposed at 700°C; however, a high content of moisture (>50%) and oxygen (>45%) resulted in a low calorific value. Thermogravimetric analysis demonstrated that the higher the heating rate and the smaller the particle size, the higher the peak and final reaction temperatures. The least squares estimation for a first-order reaction model was used to study the degradation kinetics. The values of activation energy increased from 61.14 to 73.76 and from 40.06 to 47.99kJ/mol when the EFB particle size increased from 0.3 to 1.0mm for holocellulose and lignin degradation stages, respectively. The fuel characteristics of EFB are comparable to those of other biomasses and EFB can be considered a good candidate for gasification.
空果串（EFB）是棕榈油工业的一种废物，经过热解和气化处理。高挥发分含量（>82%）增加了 EFB 的反应性，超过 90%在 700°C 下分解；然而，高水分含量（>50%）和氧气含量（>45%）导致低热值。热重分析表明，加热速率越高，颗粒尺寸越小，峰值和最终反应温度越高。使用一阶反应模型的最小二乘估计来研究降解动力学。当 EFB 颗粒尺寸从 0.3 毫米增加到 1.0 毫米时，纤维素和木质素降解阶段的活化能分别从 61.14 增加到 73.76kJ/mol 和从 40.06 增加到 47.99kJ/mol。EFB 的燃料特性可与其他生物质相媲美，EFB 可被视为气化的良好候选物。
