Comparative Studies of Extraction Products from Brown Coals

The samples of humic acids (HAs), hymatomelanic acids (HmAs), humus acids (HuAs), and fulvic acids (FAs) and residual coals were obtained by extraction from brown coals of the Kansk-Achinsk and South Ural coal basins. The fractions of humic substances were studied using Fourier transform IR and ¹³C NMR (CPMAS) spectroscopy, technical analysis, and elemental analysis. It has been established that all fractions of humic substances had individual elemental and structural group compositions.

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.
