研究了模型脂肪酸油酸在390-450℃温度范围内，在有水和无水条件下的热裂解。考察了水对转化率和产物分布的影响。用气相色谱和质谱仪对热解产物进行分析，发现液体产物中存在预期的化合物，如烷烃、烯烃、环烃、芳香烃和脂肪酸。结果表明，不同种类化合物的分布主要取决于反应温度。在无水条件下，脂肪酸热裂解产物在430℃和450℃时的液体生成量低于390℃，而芳香族化合物和固体残留物含量高于390℃，但这些反应仍表现出高转化率和低脂肪酸含量。在有水的情况下，液体产物的产率比在没有水的情况下进行的热解有所增加。然而，这种存在..。
The thermal cracking of oleic acid, a model fatty acid, in the temperature range of 390–450 °C was studied in the presence and absence of water. The effect of water on conversion yield and product distribution was determined. Analysis of the pyrolysis product by gas chromatography and mass spectrometry revealed the presence of expected compounds such as alkanes, alkenes, cyclic hydrocarbons, aromatics, and fatty acids in the liquid product. The results showed that distribution of the different classes of compounds was mainly dependent on the reaction temperature. In the absence of water, the products generated from pyrolysis of fatty acids at 430 and 450 °C yielded lower volumes of liquid product and higher amounts of aromatic compounds and solid residues than at 390 °C. However, these reactions still displayed high conversion and low fatty acid content. In the presence of water, an increase in liquid product yield was measured compared to pyrolysis conducted in the absence of water. However, the presence...
