炭化可以提高煤的利用率。孔隙结构是煤及其炭化产物半焦、焦炭物理结构的主要特征。在这项工作中，我们进行了原位小角X射线散射（SAXS）研究高温（1200 ℃）的一种褐煤和一种次烟煤的炭化。煤的孔结构（包括孔径分布、孔隙率和比表面积）的变化说明了炭化过程的不同阶段。
Carbonization can enhance the utilization of coal. Pore structure is the main feature of the physical structure of coal and its carbonization products as char and coke. In this work, we performed an in-situ small angle X-ray scattering (SAXS) study on high temperature carbonization (1200 degrees C) of a kind of lignite and a kind of sub-bituminous coal. The variation of pore structure including pore size distribution, porosity and specific surface area of coal illustrates the different stages of the carbonization process.
