ISOLATION, IDENTIFICATION, AND CORRELATION OF PORPHYRINS IN CONTINENTAL CRUDE OIL, SOURCE ROCK, AND SOME CHINESE OIL SHALE AND COAL

Scientiflc Research Institute of Petroleum Exploration & Development, Ministry of Petroleum Industry

摘要: 本文试图采用溶剂抽提、柱层析、旋转离心薄层层析、紫外可见分光、萤光分光、液相色谱、色谱-质谱等手段,对我国胜利、冀中、辽河、江汉等油田的原油及抚顺、茂名的油页岩、煤炭等样品中的卟啉化合物进行分析鉴定和研究,找出他们之间的特性和共性,以探讨原始有机质的演化及其地球化学环境.

Abstract: This paper deals mainly with the methodology of the isolation, identification of porphyrins in solvent extraction, TLC, HPLC, GC-MS, UV-visible, and fluorescence spectrophotometry applicable to the crude oils and source rocks of Senli, Ji Zhong, and Liao He Oilfield, as well as oil shales and coals of Fusuin and Myomin basins. Correlation of these oil fields data and the differences among them suggest the following: l.Free porphyrin type based on visible absorption spectrophotometry is of mixed type for crude oil and source rock; is of DPEP for oil shale; is of Etio for coal. 2.Ratio of DPEP/Etio is 2.2-3.4 for crude oil and source rock; is 4.5 for oil shale; is 0.3 for coal. 3.Maximum mass abundance of porphyrin molecules is 462 for crude oil and source rockj is 476 for oil shale; is 478 for coal. 4.Concentration of metal porphyrins is 53-424 ppm for crude oil; is 2.2-31 ppm for oil shale; is 0.25-2 ppm for coal.
