摘　　要：采用^(13)C-NMR技术表征出汪清三个矿区油页岩的碳原子化学结构,并获得碳骨架结构的12个重要参数。利用热重和傅里叶红外联用技术(TG-FTIR)得出了在50℃/min升温速率和热解终温600℃下油页岩热解时轻质气体的生成规律。采用基于燃料化学结构的FLASHCHAIN模型对热解产物的析出进行了模拟,并与实验结果相比较。结果表明,FLASHCHAIN模型用来模拟汪清油页岩热解时,在520℃之前有较好的效果,当温度高于520℃时,由于二次热解反应及页岩中矿物质分解对热解过程的影响,导致模型的预测值与实验值存在一定的误差,且随着温度的升高两者之间的误差也随之加大。The carbon atom chemical structure of three Wangqing oil shales was characterized by 13C-NMR techniques,and twelve important parameters of the carbon skeleton structure were obtained. Thermogravimetric-Fourier transform infrared spectroscopy（ TG-FTIR） tests were used to obtain the formation of light gases during pyrolysis at 50 ℃ / min and the final temperature of 600 ℃. The FLASHCHAIN model,which was established based on the structure of fuel,was employed to simulate the evolution of pyrolysis products and compared with the experimental tests. The results showthat the model has a good simulation below520 ℃,some errors occur above 520 ℃ due to the influence of secondary pyrolysis reactions and decomposition of minerals in the shale. The errors increase gradually with the increasing pyrolysis temperature.
