【摘要】：利用测试技术对广东茂名油页岩分别进行~(13)C-NMR和TG-FTIR实验,并获得12个碳骨架结构参数,得到了焦、CO_2、CH_4及页岩油随温度变化的曲线规律,同时使用非线性最小二乘法求出动力学参数。通过构造基于燃料化学结构的FLASHCHAIN、FG-DVC及CPD模型,然后对油页岩样品在50℃/min加热速率的条件下,整合实验对油页岩的焦产量、页岩油及轻质气体含量进行模拟预测,最后对样品进行全面的误差分析。结果证实,以上3个模型的预测准确度均是一级精度,证明误差都在可控的范围内,但是在焦与焦油的预测过程中CPD模型预测要比其他两种模型更加准确,在轻质气体的预测中FLASHCHAIN模型精度最高。
[Abstract]:The ~ (13) C-NMR and TG-FTIR experiments were carried out in Maoming oil shale of Guangdong province by means of testing technique, and 12 parameters of carbon skeleton structure were obtained. The curves of the variation of CO _ 2C _ 2 Ch _ 4 and shale oil with temperature were obtained, and the kinetic parameters were obtained by nonlinear least square method. A FLASHCHAINI FG-DVC and CPD model based on fuel chemical structure was constructed, and then the oil shale samples were simulated and predicted by integrated experiments under the heating rate of 50 鈩，
