煤中单组分湿式高压釜热模拟实验研究——以海拉尔盆地伊敏组褐煤为例

该文对海拉尔盆地伊敏组(J₃)煤中的有机显微组分进行了湿式高压釜热模拟实验研究。结果表明,基质镜质体是最为重要的生烃母质,其主要成烃期为270～330℃,最大生液态烃量为19mg/g、生气态烃量为256mL/g;孢子体的主要成烃期为300～380℃,最大生液态烃量为40mg/g、生气态烃量为265mL/g;而丝质体生液态烃极少,在300℃时最大也达不到2mg/g,生气态烃量为120～160mL/g。另外该方法与无水该条件下的热模拟相比,排烃高峰温度大为降低,一般要低50～100℃; 

THERMAL SIMULATION EXPERIMENT RESEARCH OF SINGLE MACERAL IN COALS WITH A WATERED PRESSURE VESSEL-AN EXAMPLE OF BROWN COAL IN THE YIMIN FORMATION OF THE HAILAR BASIN

In this paper, the thermal simulation experiment with watered pressure vessel was used to study the organic macerals in coals of the Yimin Formation (J₃) of the Hailar Basin. The experiment results showed that desmocollinite was the most important hydrocarbon-generating source material with the main hydrocarbon-generating stage of 270-330℃ as well as the maximum liquid hydrocarbon yield of 19mg/g and gaseous hydrocarbon yield of 256mL/g, the main hydrocorbon-generating stage of sporinite was 300-380℃ with its maximum liquid hydrocarbon yield of 40mg/g and gaseous hydrocarbon yield of 265mL/g, and fusinite yielded hardly liquid hydrocarbon with its maximum liquid hydrocarbon yield below 2mg/g even at 300℃ and its gaseous hydrocarbon yield of 120-160mL/g. Compared with the water-free thermal simu-lation method, the peak hydrocarbon generation temperature of this method dropped obviously, commonly about 50-100℃.
