对于抚顺及茂名沛页岩(粒径范围:0～60mm),利用单块页岩热解反应装置,以三种升温速率(1℃/min、2℃/min及5℃/min)进行了热解实验,得到了不同温度下热解总失重、页岩油收率、干馏气体收率及其组成等实验数据.考察了诸因素(粒度、升温速率、加热温度和载气流量)对热解过程的影响,发现加热温度、粒度以及升温速率是热解过程的主要影响因素.首次建立了包括传热因素在内的热解反应动力学模型,求得了块状页岩的热解总失重、热解出油及产气过程的动力学参数.结果表明:热解总失重、热解出油及产气过程的表观活化能分别约为105～120kJ/mol、125～165kJ/mol及100～120kJ/mol.
For Fushun and Maoming Pei shale (particle size range: 0 ~ 60mm), a single shale pyrolysis reaction was carried out at three heating rates (1 ℃ / min, 2 ℃ / min and 5 ℃ / min) Pyrolysis experiments were carried out to obtain the pyrolysis total weight loss, shale oil yield, dry distillation gas yield and its composition and other experimental data at different temperatures.The effects of various factors (particle size, heating rate, heating temperature and carrier gas flow) The results show that heating temperature, particle size and heating rate are the main influencing factors in the pyrolysis process.The pyrolysis kinetic model including heat transfer factor was established for the first time, and the total pyrolysis weight loss , Kinetic parameters of pyrolysis oil production and gas production process.The results show that the apparent activation energy of pyrolysis total weight loss, pyrolysis oil production and gas production process are about 105 ~ 120kJ / mol, 125 ~ 165kJ / mol and 100 ~ 120kJ / mol.
