The oxidation of coal from the Pokrovskoe mine consists of stages of initial and intense oxidation in both laboratory and natural conditions. The oxidation temperature has a significant influence on the properties of the coal. In laboratory oxidation, the surface layer of the coal grains is...
Trace elements are standard indicators of coal quality. Their distribution in coal is determined by means of the petrographic composition and ash content. However, despite extensive research, the dependence of the trace-element concentrations on these parameters has not been established....
Analysis of the chemical composition of solid fuel permits the identification of the optimal proportions of its components for effective heat generation. Kinetic analysis of the oxidation of the carbon in the coke, by means of the complete curve obtained in differential scanning calorimetry with...
The flocculation of coal fines using synthetic anionic flocculants based on acrylamide is considered. It is established that acrylamide may compete with water molecules at hydroxyl and carboxyl centers of the coal surface, to form molecular complexes with a hydrogen bond. Thanks to the presence...
The kinetics of coke deposition on catalysts for the hydrotreating of fuel fractions depends on the method used in sulfiding the catalysts. Synchronous thermal analysis may be applied to the coking of sulfided hydraulic-purification catalysts. A method is outlined for sulfiding of the catalyst...
The modification of polymer–bitumen binders by finely crystalline paraffin waxes produced by the Fischer-Tropsch gasification of coal is considered. Such modification is widely used in highway construction in the United States and Europe. Recently, paraffin waxes (FT paraffins) have become...
