摘要/Abstract

摘要： 采用法国Setaram公司Themys HP型高压热重仪对我国龙口油页岩进行不同压力条件下的热解实验，利用产物释放特性指数，并通过分布活化能模型DAEM对不同压力条件下的热解反应进行动力学分析。研究表明龙口油页岩的热解主要包括页岩的脱水阶段、有机质热解阶段以及碳酸盐及黏土矿物的分解阶段；压力的升高对于龙口油页岩的热解过程有明显的影响，改变热解产物的析出速率，产物释放特性指数能很好地表征龙口油页岩在压力改变的条件下热解过程中产物的析出特性，热解压力小范围的升高（<5bar）有利于挥发分的析出，过高的压力不利于挥发分的快速析出。动力学分析表明，热解低温阶段反应所需活化能在压力升高的条件下呈现出先增大后减小的趋势，但明显高于高温段热解活化能。适当提高压力有利于热解反应的进行。

Abstract: The Themys HP high pressure thermogravimetric analyzer from France Setaram company was used to analyze the Longkou oil shale in China under different pressures.Using product characteristic index,the distributed activation energy model DAEM and pyrolysis kinetics characteristics were analyzed.The study found that the pyrolysis of Longkou oil shale was mainly consisted of shale dehydration stage,the stage of organic matter pyrolyzed, and the stage of carbonate and clay minerals decomposed. The rise of pressure had a great effect on the behaviors of Longkou oil shale.The pressure increase in a small scale had adverse effects on the precipitation of pyrolysis products.The product characteristic index could be used to characterize product releasing behavior for Longkou shale with the condition of pressure changes.The pressure increase(<5bar)was beneficial for volatile releasing,but it suppresses volatile releasing if the pressure was higher than 5 bar.Thermal dynamics analysis showed that pyrolysis reaction activation energy decrease with the increase of pressure.Pyrolysis reaction would be improved if the pressure was properly increased.
