摘要

摘要利用物理方法（SAXS、TEM 和 XRD 分析）和选择性溶解的化学过程测定了褐煤结构中主要矿物化合物的粒度。结果表明，褐煤结构中的钙和镁化合物以小纳米颗粒的形式存在，大小约为 10 纳米。由铝和铁化合物组成的颗粒尺寸较大，约为 20-35 纳米。褐煤结构中的含硅颗粒大小为 100 纳米或更大。

A Particle Size Study of Natural Mineral Compounds in Lignite

The particle sizes of main mineral compounds in the structure of lignite were determined using physical methods (SAXS, TEM, and XRD analysis) and chemical processes of selective dissolution. It has been shown that calcium and magnesium compounds in the structure of lignite were present in the form of small nanoparticles with sizes of about 10 nm. Particles consisting of aluminum and iron compounds had larger sizes of about 20–35 nm. Silica-containing particles in the structure of lignite had sizes of 100 nm or greater.

期刊介绍： The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
