1. Hydrous desmocollinite and exinite in coal are the principal material for hydrocarbon generation.
   另外，本文提出了煤的有机地化参数类比系数法，并对煤生烃潜力进行了评价。
2. The organic source rocks of Paleogene from Huangxian basin are rich in the content of exinite and sapropelinite,especially resinite and alginite.
   黄县盆地下第三系有机岩中含有丰富的壳质组和腐泥组,尤其发育树脂体和藻类体,这些富氢组分的荧光性质各不相同。
3. The main hydrocarbon-generating macerals in the source rocks of the coal measures are exinite, alginite and desmocollinite.Organic matter is dominantly of type III kerogen.
   煤系烃源岩中主要的成烃显微组分是壳质体、藻类体、基质镜质体等,有机质类型以Ⅲ型为主;
4. Results show that hydrogen-rich macerals are disintegrated while other macerals like fusain, and exinite are resistant to disintegration.
   结果表明：富氢煤的显微组分被分解，而丝炭和角质等煤的显微组分难分解。
5. Three maceral groups,vitrinite,fusinite and exinite,seperated from Britain coal and their gasification kinetics in CO2 have been investigated by TGA at the pressure of 0.
   对英国煤进行了显微组分的分离富集，得到了镜质组、丝质组和稳定组三种富集物。
