The high bitumen yield up to 80% of kerogen by super-critical fluid extraction of oil shale, the good agreement of H/C and infrared spectra between the kerogen, bitumen and demineralized extracted residue, suggest that the major part of kerogen is a kind of polymer. Under the experimental conditions of SCFE, since kerogen was swollen, depolymerized and extracted immediately by super-critical fluid (toluene) only with little secondary decomposition, the carbon skeleton of the bitumen remains nearly the...

The high bitumen yield up to 80% of kerogen by super-critical fluid extraction of oil shale, the good agreement of H/C and infrared spectra between the kerogen, bitumen and demineralized extracted residue, suggest that the major part of kerogen is a kind of polymer. Under the experimental conditions of SCFE, since kerogen was swollen, depolymerized and extracted immediately by super-critical fluid (toluene) only with little secondary decomposition, the carbon skeleton of the bitumen remains nearly the same as its parent .According to the 1H nmr spectrum, ultimate analyses and average molecular weight, the structural parameters of bitumen were calculated.Referring to the data, the carbon constitutional fraction of Maoming oil shale kerogen was estimated as follows. Aromatic C, 0.25-0.30; naphthenic 0,0.20-0.30 and paraffinic C, 0.40-0.45. For Fushun oil shale kerogen, the result is quite similar but a little higher in paraffinic C and lower in naphthenic. The aromatic rings are mainly cata-condensed and linked with naphthenic rings as in the te-tralin-type structures.The structural unit of kerogen may be described by the elution-chromatographical constituents, their molecular ratio and molecular weights, then the structural unit weight of the Maoming kerogen had been estimated about 4500. Its chemical formula may be written as C302H440O23N6S2.

茂名和抚顺油页岩在本文第一部分所列条件下的各次抽出物的元素分析、红外光谱分析、冲洗色谱组成分析和~1H核磁共振波谱分析,其结果相接近。可以认为其油母质主要部分是一种聚合物。茂名油页岩油母质碳骨架结构族组成的近似值为:芳碳率0.25—0.30,环烷碳率0.20—0.30,链烷碳率0.40—0.45。估算茂名油母质结构单元的分子量约为4500,推定其化学式为C_(302)H_(440)O_(23)N_6S_2。
