黄县褐煤干酪根热解产物的定性与定量分析

Analysing Qualitatively and Quatitatively for the Flash Pyrolysis Products of Brown Coal Kerogen from Huangxian, Shandong Province

对山东黄县褐煤干酪根瞬间热裂解产物中的180个化合物进行了定性,对经200,300,350和400℃温阶生烃量热模拟实验后的残煤干酪根进行了PY/GC和PY/GC/MS分析,用质谱定性、色谱定量的方法将不同温阶的残煤干酪根热裂解产物分成3类,即脂链烃类、芳烃类和杂原子烃类,并分别对其产率作了定量研究。此外,发现样品中的二萜烷类和藿烷类化合物绝大部分是处于游离状态而没有键合在干酪根中。

180 compounds in flash pyrolysis products from kerogen of Huangxian brown coal at 600℃ are characterized in different level After hydrocarbon potential thermal simulating experiment at 200, 300, 350; 400℃, the kerogen of residuals are analysed by PY/GC and PY/GC/MS According to MS, the products(600℃ flash pyrolysis) are divided into the aliphatic, aromatic and N S O-compound types, the yield of three compounds are analysed quantitatively by PY/GC Furthermore, it is found that diterpenoids and hopanes of Huangxian brown coal are not bounded state but mostly free.
