Oil palm mesocarp fiber (OPMF) and palm frond (PF) were respectively devolatilized by pyrolysis to OPMF-oil and PF-oil bio-oils and biochars, OPMF-char and PF-char in a slow-heating fixed-bed reactor. In particular, the OPMF-oil and PF-oil were produced to a maximum yield of 48wt% and 47wt% bio-oils at 550°C and 600°C, respectively. The high heating values (HHVs) of OPMF-oil and PF-oil were respectively found to be 23MJ/kg and 21MJ/kg, whereas 24.84MJ/kg and 24.15MJ/kg were for the corresponding biochar. The HHVs of the bio-oils and biochars are associated with low O/C ratios to be higher than those of the corresponding biomass. The Fourier transform infrared spectra and peak area ratios highlighted the effect of pyrolysis temperatures on the bio-oil compositions. The bio-oils are pervaded with numerous oxygenated carbonyl and aromatic compounds as suitable feedstocks for renewable fuels and chemicals.
油棕中果皮纤维（OPMF）和棕榈叶分别通过热解转化为 OPMF 油和 PF 油生物油和生物炭、OPMF 炭和 PF 炭，在缓慢加热的固定床反应器中。特别是，在 550°C 和 600°C 时，OPMF 油和 PF 油的最大产率分别达到 48wt%和 47wt%生物油。OPMF 油和 PF 油的高热值（HHV）分别为 23MJ/kg 和 21MJ/kg，而相应生物炭的 HHVs 分别为 24.84MJ/kg 和 24.15MJ/kg。生物油和生物炭的 HHVs 与低 O/C 比值相关，高于相应生物质的 HHVs。傅里叶变换红外光谱和峰面积比突出了热解温度对生物油组成的影响。生物油中含有大量含氧羰基和芳香族化合物，可作为可再生燃料和化学品的合适原料。
