Abstract
Proximate and ultimate analysis and 13C NMR and IR spectroscopy were used to characterize the samples of brown coal from the Tyulgan deposit of the South Ural basin (TBC), the naturally oxidized form of brown coal from the Tisulsky deposit of the Kansk-Achinsk basin (TBCO), and fulvic acids obtained from it. The component composition of bitumen was studied using gas chromatography–mass spectrometry (GC–MS) analysis. Data of a study on the phytostimulating activity of fulvic acids and their mixtures with the saponifiable component of the resin of extraction bitumens in relation to wheat seeds of the Iren variety were presented. It was shown that the use of the saponifiable component of bitumen resins contributed to an increase in the phytostimulating activity.
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.
