摘要/Abstract

摘要： 通过热重-红外-质谱（TG-FTIR-MS）三机联用技术对桦甸油页岩在不同升温速率的条件下进行热解实验，计算了其挥发分气体析出阶段的动力学参数，并对整个热解过程中挥发分气体的析出特性进行了分析，获得了挥发分气体析出的红外三维谱图及CH₄、CO₂、CO、H₂O、C_nH_m和H₂共6种气体的析出速率随温度变化的规律曲线。其中甲烷作为热解析出的主要气态烃类产物，是多种反应综合作用的结果，故采用分峰拟合的方法对其在升温速率为20℃/min下的析出过程进行分析。结果表明，在300～600℃这一温度区间，甲烷的生成速率曲线可以分为4个峰，代表了4个反应类型，分别计算了其动力学参数，结合桦甸油页岩的结构特性及热解过程中其他气体析出的特性，分析了各个反应甲烷的生成机理。

Abstract: Pyrolysis of Huadian oil shale was carried out at different heating rates by thermo gravimetric-infrared-mass spectrometry(TG-FTIR-MS)and the kinetic parameters of the volatile gases were calculated. Based on the analysis of the precipitation characteristics of volatile gases,the infrared 3D spectrogram of volatile and the precipitation rates of six gases with temperature were obtained,including of CH₄,CO₂,CO,H₂O,C_nH_m and H₂. Mathane was the main gaseous hydrocarbon product and its precipitation process was analyzed by the method of peak fitting at the heating rate of 20℃/min. The results showed that the production rate curve of methane was divided into four peaks at 300-600℃,which represented four reaction types. Combined with kinetic analysis,the structural characteristics of Huadian oil shale and the evolution of other gases,the evolution mechanism of methane for each type was obtained.
