油页岩低温热解过程中轻质气体的析出特性
Characteristics of light gases evolution during oil shale pyrolysis
摘要
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, HD, MM and NM). The time-resolved light gases including H2, H2O, CO, 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.关键词
