摘要

为研究油页岩低温热解过程中轻质气体的析出特性

在热重-红外-质谱三联机上对国内有代表性的4个地区(FS、HD、MM和NM)油页岩以20℃·min-1的升温速率进行了热解实验研究

考察了H2、H2O、CO、CO2、CH4和CnHm 6种轻质气体的析出速率和累积产量随温度变化的规律。实验结果表明:油页岩轻质气体析出的温度范围在180～540℃;H2、CH4和CnHm的析出速率曲线大致相似

呈高斯分布

CO和CO2的析出速率则是先缓慢增加随后快速增加

达到最大值后又快速下降

直到析出结束

H2O的析出速率相对比较复杂

油页岩的内水、矿物质的结晶水和热解水在3个阶段析出

析出速率都是先增大

达到最大值而后减小。

Abstract

Pyrolysis experiments were conducted on a unit of thermogravimetric-infrared-mass spectrometry at heating rate of 20℃·min-1 to examine the evolution characteristics of light gases from low temperature pyrolysis of oil shale obtained from four locations (FS

MM and NM). The time-resolved light gases including H2

H2O

CO2

CH4 and CnHm were investigated for their release rates and accumulated productions varying with the change of temperature. Light gases evolved at temperatures in the range of 180—540℃. Release rate curves for H2

CH4 and CnHm mainly resembled each other

appearing in Gaussian distribution. Release rate curves for CO and CO2 smoothly increased first and then accelerated sharply. After reaching a maximum the curves dropped quickly till the end of evolution. Change of H2O release rate was complicated. Release rates of internal water

mineral water and pyrolysis water of oil shale in three stages all increased to a maximum and then leveled off.
