Abstract
Thermolysis of brown coal from the Baganur deposit (Mongolia) was studied. It was established that this coal is distinguished by the high content of gaseous component (up to 40 %) and low content of the liquid fraction (up to 7 %). The decomposition of the material starts at a temperature of about 200 °С. Within the whole heating temperature range (up to 650 °С) the material does not get agglomerated; the final product of thermolysis is loose graphite-like material.
