Thermochemical conversion is the key technology for the comprehensive utilization of Chinese oil shale resources. Oil shales from three mining areas of Huadian Jilin were pyrolyzed at 500 degrees C in a quartz tube reactor and their pyrolyzed cokes and shale oil were derived. One oil shale was also pyrolyzed at 600 degrees C and 700 degrees C to assess the influence of temperature on pyrolysates. FTIR analysis was carried out to study the raw shales and their products. The results showed that shale oil had similar functional groups as the organic matter of oil shale, mainly aliphatic hydrocarbon, and the shale oil contained more of it than the raw material. The shale with more aliphatic oil yielded more oil. That with less aliphatic and more aromatic one yields less oil, and its coke is rich in condensed aromatics. Pyrolysis was almost completed at 500 degrees C. Oil yield did not increase further with temperature, but secondary pyrolysis strengthened. At 700 degrees C carbonates began to decompose.
热化学转化是中国油页岩资源综合利用的关键技术。对吉林桦甸三个矿区的油页岩在石英管反应器中于500℃下进行热解，并得到其热解焦炭和页岩油。还对一种油页岩在600℃和700℃下进行热解，以评估温度对热解产物的影响。采用傅里叶变换红外光谱（FTIR）分析研究了原始油页岩及其产物。结果表明，页岩油与油页岩有机质具有相似的官能团，主要为脂肪烃，且页岩油中脂肪烃的含量高于原料。脂肪油含量较高的页岩产油量更高。脂肪烃含量较低而芳烃含量较高的页岩产油量较低，其焦炭富含稠环芳烃。在500℃时热解基本完成。产油量不会随温度进一步增加，但二次热解增强。在700℃时碳酸盐开始分解。
