摘要

摘要: 通过煤岩及其各显微组分等6个系列以50℃为一温阶,从250～550℃进行热模拟实验,对其气体产物进行了系统分析。结果表明:随着温度的升高,煤岩及其各显微组分产气率均呈增长趋势;不同的模拟物质,在同一温度下产气率各不相同;同一模拟物质,在不同温度下产气率亦不同;其中镜质组和壳质组具有较强的产气潜力,丝质组和半丝质组产气量甚低,而全煤表现为各显微组分成烃的综合效应。气体产物中CO₂和N₂主要在低温阶占比例较大。

Abstract: The coal rock and its marceral six series of samples were conducted a thermal simulation experiment.The temperature was programmed from 250 to 550℃ with a temperature step of 50℃.The gas products were analyzed systematically.The results show that the gas production rate is increasing with temperature for the coal rock and its marceral,is varied at the same temperature for different simulated material,and is different under various temperature for the same simulated material.It is also revealed that the vitrinite and exinite have stronger gas potential,the gas production of the fusinite and semifusinite is very low,and the bulk coal samples display the synthetic hydrocarbon-generating effects of each marceral.CO₂ and N₂ make up larger percentage in the gas products mainly within low temperature bands.
