重餾份石油芳香烴族組成質譜分析方法Fouriertransformation infro - red microspectroscopy micro - ftir technique was used to investigate the chemical compositions and structures of cutinite, vitrinite and fusinite from jurassic coals in tarim basin at different temperatures. the results show that the chemical structure of cutinite is mainly composed of long aliphatic - side chain with minor amounts of aromatic compounds. vitrinite is mostly composed of aromatic compounds, in addition to large amount of short aliphatic - side chain compounds. whereas fusinite are dominant by aromatic structure. the study indicates that cutinite is one of the best oil source - rocks, with the higher hydrocarbon - generation potential ; vitrinite is one of better gas source - rocks, and has medium hydrocarbon - generating potential ; fusinite has little hydrocarbon - generating potential. in addition, the components of aliphatic structures of cutinite, vitrinite and fusinite decrease, the aromatics are enriched and condensation of aromatic structure increases with increasing the temperature, and along with the rise of temperatures, the intensity of aliphatic structure and heteroatomic compounds decrease obviously, however the aromatic structure changes a little
應用顯微紅外光譜技術,對塔里木盆地侏羅紀煤中有代表性的3種組分角質體鏡質體絲質體在不同熱模擬溫度下的結構組成變化特徵進行了研究,結果表明:角質體結構組成中含有較豐富的長鏈脂族結構,而芳香結構和含氧官能團的含量則相對較少與此相反,絲質體結構組成中芳香烴占絕對優勢,而脂族結構含量則很少鏡質體結構組成介於角質體和絲質體之間,含有較多的短鏈脂族結構和芳香結構。Organic geochemical measurements of geological samples - method for aromatic types analysis of gas - oils aromatic fractios by mass spectrometry
