Abstract

ABSTRACT Carbonisation is an important way of comprehensive utilisation of coal. In this short contribution, the application of wide angle X-ray scattering (WAXD) and radial distribution function (RDF) in coal carbonisation research is briefly reviewed and prospected. General WAXD analysis can only provide basic geometrical structural parameters of crystals in the sample; while RDF derived from WAXD by Fourier transform can give further detailed structural parameters of coordination of atoms in sample. The application of RDF in coal science has been reported in offline static studies, but not in-situ studies. Here, a new ideal to perform in-situ RDF study on coal carbonisation is presented, which is based on a powerful synchrotron radiation platform with a proper detector and a high-temperature furnace. Thus, it is expected to obtain the fine dynamic structural evolution characteristics of coal during carbonisation.

径向分布函数在煤碳化研究中的应用前景

摘要炭化是煤炭综合利用的重要途径。在这篇简短的文章中，简要回顾和展望了广角X射线散射（WAXD）和径向分布函数（RDF）在煤碳化研究中的应用。一般WAXD分析只能提供样品中晶体的基本几何结构参数；而通过傅立叶变换从WAXD中导出的RDF可以进一步给出样品中原子配位的详细结构参数。RDF在煤炭科学中的应用已经在离线静态研究中报道，但没有在现场研究中报道。在这里，提出了一种新的理想方法来对煤的碳化进行原位RDF研究，该方法基于一个强大的同步辐射平台，该平台配有合适的探测器和高温炉。因此，有望获得煤在碳化过程中精细的动态结构演化特征。

期刊介绍： Philosophical Magazine Letters is the rapid communications part of the highly respected Philosophical Magazine, which was first published in 1798. Its Editors consider for publication short and timely contributions in the field of condensed matter describing original results, theories and concepts relating to the structure and properties of crystalline materials, ceramics, polymers, glasses, amorphous films, composites and soft matter. Articles emphasizing experimental, theoretical and modelling studies on solids, especially those that interpret behaviour on a microscopic, atomic or electronic scale, are particularly appropriate. Manuscripts are considered on the strict condition that they have been submitted only to Philosophical Magazine Letters , that they have not been published already, and that they are not under consideration for publication elsewhere.
