The experiment on evolution of hydrocarbon-generation in organic macerals of coal
-
摘要: 热解模拟实验揭示,镜质组的生烃作用与其起始成熟度有关,如果初次生烃中止,成熟度 (再次生烃起始成熟度)尚未超过生油高峰阶段 (R=0.9%),则再次生烃有可能显著提高煤的生烃潜量,且以起始成熟度在生烃高峰处的升高幅度为最大。在有机显微组分中:壳质组的生烃量最大,生烃范围最集中;镜质组次之;惰质组最少。Abstract: Based on the pyrolytic simulation experiment,the vitrinite's hydrocarbon-generation in coal related to its starting maturation. If the first hydrocarbon-generation is end and the maturation (starting maturation of the rehydrocarbon-generation) has not been exceed the oil-forming peak(R=0.9%), the rehydrocarbon-generation can greatly increase the potential of hydrocarbon-generation of coal, and when the starting maturation locate at oil-forming peak stage, the potential of hydrocarbon-generation is the biggest. Contrasting the three types of organic macerals in coal, the exinite of hydrocarbon-generation is the greater, the vitrinite is second and the inertinite is the least.
