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

富氢煤的分被分解，而丝炭和角质等煤的分难分解。

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

西北地区侏罗纪煤地层中主要的生烃分体、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。

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.
