Abstract

Oil shale (OS) is a solid hydrogen rich fossil fuel whose organic part can, under appropriate conditions, be turned into liquid fuel. The obtained shale oil is a mixture of a large number of organic compounds. However, the exact composition and yield of shale oil depend not only on the composition of oil shale, but also on the type of the reactor where oil was produced, as well as on process parameters like heating rate, pyrolysis temperature, pyrolysis time, and the size of oil shale particles fed to the reactor. In this paper, we present the results of the full chemical analysis of Estonian Ojamaa oil shale – characteristics of oil shale and shale oil and distribution of sulfur. The results of ultimate, proximate, major components and pyrolysis mass balance analyses are also presented and the characteristics of crude shale oil and oil fractions are provided. Special emphasis is put on the analysis of sulfur and its distribution between the pyrolysis products. Additionally, thermogravimetric analysis (TGA) results are provided.
油页岩热解产物与硫的命运
油页岩(OS)是一种固体富氢化石燃料,其有机部分在适当条件下可以转化为液体燃料。得到的页岩油是大量有机化合物的混合物。然而,页岩油的确切组成和产量不仅取决于油页岩的组成,还取决于产油反应器的类型,以及加热速率、热解温度、热解时间、进给反应器的油页岩颗粒大小等工艺参数。在本文中,我们介绍了爱沙尼亚奥哈马油页岩的全化学分析结果——油页岩和页岩油的特征以及硫的分布。给出了终值分析、近似分析、主组分分析和热解质量平衡分析的结果,并给出了页岩原油和油分的特征。重点介绍了硫的分析及其在热解产物中的分布。此外,还提供了热重分析(TGA)结果。
