maceral

1.Results show that hydrogen-rich macerals are disintegrated while other macerals like fusain, and exinite are resistant to disintegration.

富氢煤显微组分被分解，而丝炭和角等煤显微组分难分解。

2.Main macerals of hydrocarbon generation are sporinite, cutinite, alginite, bituminite, liptodetrinite and desmocollnite in source rocks from Jurassic coal measure in Northwest China.

西北地区侏罗纪煤系地层中主要显微组分是孢子、角、藻类、沥、碎屑类脂、基镜等，而树脂、木栓等早期低熟油组分含量很低。

3.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分离富集，得到了镜组、丝组和稳定组三种富集物。
