摘要

利用高压釜反应装置，对柳树河油页岩进行了热压模拟实验研究，考察了饱和水介质条件下油页岩的热解动力学。利用不同温度下热解产物的实验数据，建立了以沥青为中间产物的连串一级反应的动力学模型，得到了相关的动力学参数，结果表明，油母质热解生成热沥青的活化能约为110 kJ·mol-1，低于热沥青进一步分解生成页岩油的活化能（约为190 kJ·mol-1），说明油母质热解生成热沥青的反应更容易进行。根据实验数据和动力学结果，对油页岩的热解机理和水介质的影响进行了初步探讨。结果表明，在饱和水介质条件下，油页岩的热解温度比无水条件时降低了约120℃。

Abstract

The hydrous thermo-simulation experiments on Liushuhe oil shale were conducted in autoclave.Consecutive first order reaction model involving bitumen as an intermediate product was developed to determine the kinetic parameters.It was found that the apparent activation energy of kerogen pyrolysis was about 110 kJ·mol-1

which was lower than the apparent activation energy of bitumen pyrolysis.According to the results

the mechanism of oil shale pyrolysis and the influence of aqueous medium were tentatively investigated.Compared to anhydrous pyrolysis

the maximum pyrolysis temperature under saturated condition was about 120℃ lower.
