Abstract—Changes in the composition of the organic matter of brown coal upon mechanical treatment under
conditions of elevated temperatures (80–200C) were studied. The mechanical treatment of coal was performed
on an AGO-2 mill in an atmosphere of argon. A VT8-2 thermostat was used to maintain a specified temperature
in the course of the experiment. Based on an analysis of IR spectra, it was found that the composition of ali-
phatic hydrocarbons was changed in the course of mechanical treatment (regardless of temperature). The
mechanical treatment of coal at 80–200C was accompanied by the release of methane and ethane at 200C. As
the mechanical treatment temperature was increased to 160C, the yield of chloroform bitumoid from coal
increased. The noticeable degradation of hydrocarbons came into play starting with a mechanical treatment
temperature of 200C.
