采用半封闭体系对神府煤以50 ℃为一温阶,从250 ℃～500 ℃进行了生烃热模拟实验,探讨了生烃热模拟过程中气态产物、液体油以及固体产物的演化特征.结果表明,生油高峰在400 ℃～450 ℃之间,最高生油率为41.2 mg/g.生气高峰在500 ℃,最高生气率为99.4 mL/g.气态烃以CH_4为主要成分,占总生气量的33.6%～61.2%.非烃气体以H_2为主,占总生气量的18.5%～58.1%.非烃气体主要形成于早期阶段,含有部分CO_2以及少量CO.固体产物中的碳元素含量增加,氢和氧含量降低.

CT Through the thermal simulation experiments of hydrocarbon generation in the semi-closed system on Shenfu coal and the coal with different mediums from 250 ℃ to 550 ℃, with a stepwise heating stage of 50 ℃, the characteristics of gas, liquid and solid products are discussed systematically in this paper. The results show that the peak yield of oil appears between the heating temperature 400 ℃ and 450 ℃, the maximum oil-generating ratio is 41.2 mg/g. The maximum gas-generating ratio is 99.4 mL/g at 500 ℃. Methane is predominant component of the hydrocarbon gas, reaches to 33.6%-61.2% of the total gas yield. Hydrogen is the main part of the non-hydrocarbon gas, achieves to 18.5%-58.1% of the total gas yield. Non-hydrocarbon gas is generated in the early stage, partial carbon dioxide and smidgen carbon monoxide in them. The content of C in the solid products increases and the content of H,O decreases.
