摘要/Abstract

摘要： 运用低温灰化仪、热重-红外联用分析仪对3种内蒙古油页岩进行低温灰化和以20℃/min升温速率的热解实验，来探究低温灰化对油页岩热解特性的影响。通过热重（TG-DTG）曲线、红外分峰拟合曲线分析低温灰化前后官能团的变化，并考察了CO₂、CH₄、C_nH_m轻质气体随灰化时间的变化规律。结果表明：热解实验过程中，低温灰化后不同有机质含量的油页岩和原样的热重曲线有差别之处，灰样在第二阶段则趋于平缓，失重比例小，且随着灰化时间的增加，灰样的热重曲线逐渐向高温区移动。内蒙古油页岩原样的热解产物主要是CO₂和CH₄、C_nH_m，而灰样中轻质烷烃和芳香烃的含量均减少；内蒙古油页岩析出气体CH₄和C_nH_m曲线基本相似，呈高斯分布，CO₂的析出速率先缓慢增加后快速增加，达到最高值后又快速下降，直至析出结束。同时，对内蒙古油页岩和灰样进行热解动力学的研究，反应的活化能通过Coats-Redfem积分法进行分析，得出热解的化学反应动力学参数，其计算结果为油页岩的高效开发和经济利用提供了理论基础。

Abstract: The influence of low temperature ashing on pyrolysis characteristics of 3 Inner Mongolia oil shales was studied according to the pyrolysis experiments of gravimetric-infrared-mass spectrometry at heating rate of 20℃/min by using low temperature ashing instrument and thermo gravimetric-infrared analyzer.The changes of functional groups before-and-after low temperature ashing and the light gases including CO₂,CH₄ and C_nH_m were investigated by thermo gravimetric curve (TG-DTG) and infrared peak fitting.The experimental results showed that the weight loss of ashing sample was gently with less proportion of weight loss in the second stage.With increasing ashing time the TG curves of ashing sample moved to high temperature and the weight loss was reduced.For different organic matter content of sample and ashing sample infrared peak fitting.The pyrolysis products of Inner Mongolia shales were similar in CO₂,CH₄ and C_nH_m for both original and ashing samples,while the contents of light paraffin and aromatic were reduced in ashing sample.Both were quite same in release rate curves for CH₄ and C_nH_m with Gaussian distribution.The release rate curves for CO₂ smoothly increased first and then accelerated sharply,and after reaching a maximum the curves dropped quickly till the end of evolution.At the same time,the research of pyrolysis kinetics for Inner Mongolia shale and ashing samples showed that the activation energy can be calculated by using Coats-Redeem method.The obtained chemical reaction kinetics parameters of pyrolysis provided a theoretical basis for the efficient development and economic utilization of oil shale.
