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分的分离富集，得到了镜质、丝质定三种富集物。

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

西地区侏罗纪煤系地要的生烃显微分是孢子体、角质体、藻类体、沥青质体、碎屑类脂体、基质镜质体等，而树脂体、木栓质体等早期低熟生油分含量很低。

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

富氢煤的显微分被分解，而丝炭角质等煤的显微分难分解。
