Abstract
The composition of the products of mechanical treatment (MT) of a mixture of brown coal and water (1 : 1) at MT temperature of 80, 120, 160, 200 °С was investigated. MT of the water - coal system was carried out with the help of AGO-2 installation in the atmosphere of argon. Mechanical treatment at increased temperatures promotes the destruction of the organic component of brown coal. It is demonstrated that an increase in MT temperature causes a decrease in methane yield and an increase in the yield of bitumoid. The content of resins and asphaltenes in bitumoids was determined to increase with an increase in MT temperature. The ignition and combustion characteristics of the products of mechanically treated coal-water mixture were studied.
