In situ change of fractal structure in coal with coking capability during high-temperature carbonisation
ABSTRACT Coal is an important energy and chemical raw material. Carbonization is an effective way for comprehensive utilization of coal, especially for coal with coking capability. The complex pore structure of raw coal and its carbonization solid products can be well characterized by a fractal description. Owing to a lack of in situ studies, the change in the fractal structure of coal with coking capability during carbonization remains unclear. Here we report briefly on an in situ study on high-temperature (1000°C) carbonization of four kinds of Chinese typical bituminous coal with coking capability, namely gas coal, fat coal, coking coal and lean coal, by synchrotron radiation small-angle X-ray scattering (SAXS). The change of fractal structure of the coal is analyzed in terms of corresponding mechanisms.
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.
