  • Method of liquefaction of brown coal

    FIELD: processing brown coal by thermal liquefaction in organic solvents. SUBSTANCE: proposed method consists in mechanoactivation of brown coal under pressure in cavitation apparatus together with water-and-coal suspension at coal-to-water ratio equal to 30-60 mass-% at temperature of 15-70°C, rotor speed of 3000-12000 per minute continued for 5-50 cycles.

  • THERMOGRAPHIC INVESTIGATIONS OF THE MINERAL FRACTION .

    The results are given of thermographic investigations of fractions of different densities isolated from the coals of the Nazarovo, Irsha-borodino, and Berezovka deposits of the Kansk-Achinsk brown-coal basin (USSR). The characteristics of the mineral fraction of the coals investigated and its behavior on heating have been determined.

  • The Impact of Microwaves of Different Timing on the ...

    Changes in the properties of brown Kansk-Achinsk coal after exposure to microwaves have been studied using scanning electron microscopy (SEM) and electron magnetic resonance (EMR). The size composition of the samples has been investigated. The structure of coal has been found to be similar to the structure of component organic glass. The analysis of the changes in the EMR spectra of the ...

  • Steam Gasification of Different Brown Coals Catalysed by ...

    The brown coal samples from the Borodino and Bere-zovo deposits of Kansk-Achinsk Basin, Kangalas deposit of Lena Basin and a sample of brown coal from Yallourn deposit in Australia were studied. The coals were crushed, and a required fraction of 0.5 - 1.0 mm dried in a vacuum drying oven at 85˚C was used. 2.2. Acid Treatment of Coals
