南桐煤镜质组非晶结构的X射线衍射研究

X RAY DIFFRACTION STUDIES OF AMORPHOUS STRUCTURE IN VITRINITE

本文对经典煤核结构模型评述后，提出了多元非晶煤结构概念。用Ｘ射线衍射方法研究了南桐煤镜质组的原子径向分布，论证了煤大分子中同时存在芳香结构单元和脂环结构单元，它们对Ｘ射线衍射强度均有贡献，非晶煤结构的有序性不大于１ｎｍ。文中还讨论了非晶煤结构模型，以及煤结构在煤化过程中的变化规律。

After the classic structural model of coal had been reviewed,the new conceptofmulti element amorphous structure of coal was put forward The radial distribution ofatomsin coals was studied by X ray diffraction The results have shown that there are aro maticcarbon atom layers and alicyclic carbon atom layers in the macromolecules of coal,andboththe aromatic layers and alicyclic layer scatter coherently X ray,and that the order ofamorphouscoal structure is less than 1 nm The model and variation of amorphous coalstructurewere discussed in this paper
