Ultimate and proximate analyses and thermal degradation of bio-oils from pinewood and palm empty fruit bunches (PEFB) were carried out to evaluate the oils' potential for production of fuels for transport, heat and power generation, and of hydrogen via the calculation of performance indicators. The pinewood and PEFB oils indicated good theoretical hydrogen yields of 13.7 and 15.9 wt.% via steam reforming, but their hydrogen to carbon effective ratios were close to zero, and their propensity for fouling and slagging heat exchanger surfaces via combustion was high. Both oils exhibited two phases during mass loss under nitrogen flow at heating rates of 3-9 Kmin(-1), but the kinetics of their thermal degradation from TGA-FTIR analysis indicated different degradation mechanisms that were well reproduced by a nth order reaction model for pinewood and Jander's 3D-diffusion model for PEFB. These findings lead to recommendations on pretreatments prior to the oils' utilisation.
进行了松木和棕榈空果串（PEFB）生物油的终极和近似分析以及热降解，以通过计算性能指标来评估这些油作为运输、供热和发电燃料以及通过蒸汽重整生产氢气的潜力。通过蒸汽重整，松木和 PEFB 油的理论产氢量分别为 13.7%和 15.9%，但它们的氢碳有效比接近零，而且在燃烧过程中易结垢和积渣，堵塞热交换器表面。在氮气流量下以 3-9 Kmin(-1) 的升温速率进行质量损失时，两种油都表现出两个阶段，但从 TGA-FTIR 分析的热降解动力学来看，它们的热降解机制不同，这两种机制都可以通过松木的 n 级反应模型和 PEFB 的 Jander 3D 扩散模型很好地再现。这些发现为油的利用前的预处理提出了建议。
