ABSTRACT

A kukersite oil shale sample from Estonia was pyrolyzed using a Fischer assay method under N₂, N₂/steam, CO₂ and CO₂/steam environments. The thermal behavior of the oil shale sample was also studied using TGA and DSC with similar conditions. Also, several properties of produced oils were measured and FTIR analysis was carried out to compare the molecular structure of the derived oils. The presence of steam increased the liquid and gaseous yields, and also caused a greater weight loss in the oil shale. The pyrolysis tests in both the CO₂ and N₂ atmospheres produced oils with relatively similar properties however, the molecular structure was different.

摘要

_{在 N 2}、N ₂ /蒸汽、CO ₂和 CO ₂ /蒸汽环境下，使用 Fischer 分析方法热解了来自爱沙尼亚的 kukersite 油页岩样品。还使用 TGA 和 DSC 在类似条件下研究了油页岩样品的热行为。此外，还测量了产出油的几种性质，并进行了 FTIR 分析以比较衍生油的分子结构。蒸汽的存在增加了液体和气体的产量，也导致油页岩的重量损失更大。在 CO ₂和 N ₂气氛中的热解试验产生的油具有相对相似的性质，但是分子结构不同。
