Abstract
The products of thermolysis of brown coal from the Baganur deposit (Mongolia) were investigated. Only residual relics of separate hydrocarbon components of initial coal were detected in the solid residue. The liquid condensate of the sublimates (18–19 % of initial coal), which contains 0.78 mass % organic extract (96–98 % phenol and its derivatives) and 92.2 mass % of the aqueous solution, under heating boils off within temperature range 115–130 оC. The isolated organic extract under heating is transferred into vapour intensively at temperatures up to 360 оC. Initial aggregative state (particle size, degree of the action of environment) not only affect the yield of the gas component of coal during thermolysis but also determine the impurity composition of the organic extract of the liquid condensate of sublimates.
