对美洲龙舌兰（Agave americana）和辣椒（Capsicum annuum）的表皮物质在360℃下进行了长时间（72小时）的水热液化（HTL），以模拟有机物的长期成熟。这两种角质层材料都显示了从C-13固态核磁共振光谱中聚亚甲基碳的数量可能产生石油的证据。生物油的产率约为35 wt.%，热值为40.5 MJ kg(-1)，与典型原油相当。二维气相色谱分析表明，美洲金针叶生物油以同源系列正构烷烃为主，环类化合物和芳香族化合物为主要成分。进一步的电喷雾电离-傅里叶变换离子回旋共振-质谱分析表明，生物油样品主要具有类脂质的特征。这项研究的结果表明，人们可以利用某些植物材料的高脂肪族生物聚合物成分来生产生物油，这种生物油有可能被用作替代燃料。(C) 2015 Elsevier Ltd.版权所有。
Hydrothermal liquefaction (HTL) of cuticular materials from Agave americana and Capsicum annuum was performed for extended periods of time (72 h) at 360 degrees C meant to simulate long-term maturation of the organic matter. Both cuticular materials displayed evidence for possible oil production from the amounts of polymethylenic carbons in C-13 solid-state nuclear magnetic resonance spectra. The bio-oil yields were approximately 35 wt.% and exhibited heating values of 40.5 MJ kg(-1), comparable to those of typical crude petroleum. Analysis by two dimensional gas chromatography indicated that the A. americana bio-oil was dominated by a homologous series of n-alkanes, whereas cyclic and aromatic compounds were the major compounds identified in the C. annumm bio-oil. Further analysis using electrospray ionization-Fourier transform ion cyclotron resonance-mass spectrometry revealed the bio-oil samples were predominantly lipid-like in character. The result of this study demonstrate that one can utilize highly aliphatic biopolymeric components of certain plant materials to produce bio-oils that have the potential to be utilized as alternative fuels.
