摘要
The characteristic of solid 13C nuclear magnetic resonance(13C NMR) was used for the study of the chemical structures of kerogen extracted from the Yangxia coal of Jurassic in Kuqa Depression of Tarim Basin by different methods at different temperatures.The results indicate that the chemical composition of the kerogen is composed of aliphatic structure,aromatic structure and oxygenated functional group.During thermal simulation,the aliphatic structure is in seperating out,the oxygenated functional group appears to be in cracking with temperature rising,due to low activation energy,followed by producing CO2 and H2O.
