摘要

研究了褐煤样品的表面形貌和孔隙结构。发现不规则的非晶态颗粒占主导地位。根据能量色散x射线(EDX)分析结果，样品的矿物成分化学成分几乎相同。褐煤样品具有高钙含量的特点。样品的多孔结构几乎完全相同。比表面积小。孔隙空间由平均直径18 ~ 28 nm的中孔组成。

Developing Additives Based on Russian Coal for the Thermal Hydrocracking of Heavy Tar. 2. Surface Morphology and Porous Structure

The surface morphology and porous structure of lignite samples are studied. Irregular amorphous particles are found to predominate. According to the results of energy-dispersive X-ray (EDX) analysis, the chemical composition of the samples’ mineral components is practically the same. The lignite samples are characterized by high calcium content. The porous structure of the samples is practically identical. The specific surface is small. The pore space consists of mesopores of mean diameter 18–28 nm.
