Abstract
Integrated investigation of the thermolysis of black coal from the Tavantolgoy deposit (Mongolia) was carried out. It was discovered that coal decomposes during thermolysis within temperature range 300–500 °С with the evolution of gas, low-melting and low-boiling phases, intensively increases in volume and gets agglomerated. As a result, rather strong porous cake is formed. Its volume is 1.5–2 times larger than the volume of the initial sample. It was shown that coal from the Tavantolgoy deposit (without any binding additives) can be used for briquetting.
