AbstractA procedure for the construction of an approximating particle-size distribution function of a dispersed phase using a dynamic light scattering method was proposed. This procedure makes it possible to pass from the experimental spectrum in the particle size–intensity coordinates to theoretical particle size–number of particles and particle s...

AbstractThe extraction of water-soluble total alkylresorcinols from the tar water of the Kiviter shale-chemical process with methyl isobutyl ketone was studied. The effects of the volume ratio between contacting phases, the time and rate of mixing, the temperature regime, and the initial concentration of total phenols on the degree of their extract...

AbstractThe adsorption of phenol by activated carbons obtained by the alkaline thermolysis (KOH, 800°C) of fossil coals of various degrees of metamorphism (Cdaf = 70.4–95.6%) was studied. Kinetic dependences and adsorption isotherms were obtained at initial concentrations of ≤3 mg/cm3 (25°C). The rate constants of absorption of the adsorbate, maxim...

AbstractThe results of experimental studies on the selection of binders for the briquetting of anthracite fines and coal slimes available in the Rostov oblast are presented. The effects of the particle-size distribution of coal components, the binder content, the moisture content of the charge, and the specific compacting pressure on the technical ...

AbstractStructural changes in resins and asphaltenes in the course of their separate and combined cracking were studied. Cracking was carried out in a batch reactor at 450°C for 2 h. Data on the mass balance of the cracking process and the composition of liquid products were obtained, and the structural-group analysis of resins and asphaltenes was ...

AbstractA new method for the production of fuel briquettes from carbon-containing fine waste and an aqueous solution of polyvinyl alcohol under pressure was developed. It was found that a freeze–thaw cycle promotes the formation of fuel briquettes with a minimum amount of the polymer binder. Samples of high-grade fuel with high physicomechanical an...

AbstractThe thermal decomposition of various types of biofuel was investigated by pyrolytic gas chromatography. Chromatograms were obtained for 5 biofuel samples, and more than 40 components were identified and classified into 8 groups. The qualitative analysis of the pyrolysis products was performed, and the results obtained for different biofuels...

AbstractThe ignition thresholds and kinetic characteristics of the glow of flames under the action of nanosecond laser pulses (τi = 14 ns) of a YAG:Nd3+ laser (λ = 1064 nm) on coals of DG (long-flame gas), G (gas), Zh (fat), and K (coking) grades from the Kuznetsk Basin were measured. The stages associated with the evaporation of microprotrusions o...

AbstractThe calculated thermodynamic functions of a primary coal tar fraction with a final boiling point of 300°C were presented for the modeling of hydrogenation products using an additive method. Based on model reactions of the hydrogenation of o-cresol, it was demonstrated that the hydrogenation of an aromatic ring is more likely than the hydrog...
