| 中文摘要:高压-工频电加热原位裂解油页岩是吉林大学与俄罗斯托木斯克理工大学合作研究的具有占地面积小、污染小、工艺简单等优点的油页岩开采技术。先对油页岩使用高压电击穿，再使用电加热的二步法，可以达到快速裂解油页岩的效果。为了确定裂解油页岩的工艺参数，以及更好地掌握高压-工频电加热裂解油页岩技术，本文对油页岩在有、无氧气条件下的裂解过程进行了热分析试验。试验表明，在有氧与无氧加热条件下，都可完成油页岩的裂解，且裂解过程是相同的，都属于二段式裂解过程。氧在油页岩加热裂解时具有驱动作用，可以降低油页岩的裂解温度、节省能量、提高裂解速度。 |

| Abstract:A new technology of in-situ pyrolysis of oil shale by high voltage-power frequency heating is proposed by Jilin University and Tomsk Polytechnic University, Russia. It has the advantages of small footprint, less pollution and simple technology. The two-step method is to use high voltage electricity to break down oil shale, then by electric heating to realize rapid pyrolysis of oil shale. In order to determine the technical parameters of oil shale pyrolysis and master oil shale pyrolysis technology by high voltage-power frequency heating, the thermal analysis on the pyrolysis process of oil shale under the conditions of with or without oxygen are carried out. The test results show that the pyrolysis of oil shale can be completed under the aerobic and anaerobie heating conditions, and the pyrolysis processes are the same, all of which belong to two-step pyrolysis process. Oxygen plays a driving role in the pyrolysis of oil shale, which can reduce the pyrolysis temperature of oil shale, save energy and speed up the pyrolysis of oil shale. |
