| 摘 要： | 利用岩石-热解评价仪研究了200～600℃不同升温速率(10、15、20、25、30℃/min)下柳树河盆地油页岩热解生烃特征,利用Friedman法和Sestak反应机制,求出了油页岩的反应活化能和反应函数,建立了热解动力学模型,可用于计算热解生烃率和达到某一转化率所需要的时间。研究发现,油页岩的反应活化能并不是一个定值,随着反应温度的增加逐渐增大。这是因为油页岩热解是一个极其复杂的多步反应过程,在不同的温度区间内具有不同的反应机理。 |

| Abstract: | Pyrolysis kinetics characteristics of oil shale samples obtained from Liushuhe basin were investigated by Rock Eval analysis.The pyrolysis characteristics were studied at different heating rates(10,15,20,25,30 ℃/min) from 200 ℃ to 600 ℃.Based on the Friedman mathematical formula and Sestak reaction mechanism,the reaction activation energy and reaction function were obtained,and so the pyrolysis mathematical model was developed.This mathematical model can be used to calculate the hydrocarbon conversion and required times for the fixed conversion.It is found that the reaction activation energy is not a constant and is a variable with the variety of reaction temperature.The reason is that the pyrolysis reaction process of oil shale is complicated multistep reaction,in which reaction mechanism is variable in different temperature range. |
| Keywords: | mathematical model oil shale pyrolysis characteristics Liushuhe basin |
