摘要：

In an attempt to obtain a greater insight into the structure of Monterey kerogen, partially oxidized kerogen concentrates obtained from Na2Cr2O7 glacial CH3COOH stepwise oxidation were examined by Fourier transform infrared (FT-i.r.) analysis. The results show that the kerogen samples contain condensed aromatic systems to which are attached OH and Oalkyl functional groups, and also indicate that the majority of N and S atoms are within the ring structure. It was found that the carbonyl, aromatic and ether groups are not affected while CH2 groups are lost upon oxidation. Furthermore, it was concluded that in kerogen oxidation, organic sulphur can be fixed as inorganic sulphate in the presence of COO- in a manner similar to coal oxidation. © 1990.
